How to Start a Genealogy Search
Starting a search means setting a clear goal and choosing what you already know. Write down the ancestor’s name, date of birth, and last known address on paper. Decide what you hope to find, such as a parent, a death date, or a burial place. A small goal helps you stay focused as records grow. A simple notebook, a spreadsheet, or a genealogy software file can hold your notes.
Search by Ancestor Name
Name searches work best when you know the full name and any spelling used at the time. Try first name, last name, and middle name in separate searches. Check both English and native spellings if your family came from another country. A woman may appear under her maiden name on one record and her married name on another.
Search by Birth or Death Date
Date searches help narrow large result lists down to a few entries. A birth year range of plus or minus five years catches most clerical errors. Death records often give the most exact date when birth dates are missing. Census ages can be checked against date searches to confirm identity.
Search by Location
Location searches link a person to a place on a map of the county or city. Old township names differ from today’s zip codes and street names. Local histories name old streets, churches, and schools that show up in records. Plat books and Sanborn maps can help you match an address from a century ago.
Search by Family Relationship
Relationship searches find parents, spouses, children, and siblings of an ancestor. Marriage and probate records name spouses and children together on one page. Census pages show each household member with their relationship to the head of the house. Obituaries also list survivors in a clear family layout.
Information Needed to Begin Research
Gather the ancestor’s full name, birth year, death year, and last county of residence before you search. Add any known parents, spouses, or children. Bring a list of addresses, jobs, churches, and military service dates if you have them. The more facts you have, the faster you can match records.
- Full name at birth and any later name changes
- Birth year and place of birth
- Death year and place of death
- Names of parents, siblings, spouse, and children
- Last known address and occupation
Vital Records for Genealogy
Vital records list births, deaths, marriages, and divorces recorded by the county or state. They give exact dates and full names that are hard to match anywhere else. Missouri began statewide registration of births and deaths in 1910, but county records go back further in some cases. Church and cemetery records often cover the years before civil registration began. These records form the backbone of a verified family history.
Birth Records
Birth records show the date, place, and names of both parents at the time of birth. They give the attending doctor or midwife and the residence address. Earlier birth records may list only the year and township. Delayed birth records filed years later often hold the most detail.
Death Records
Death records show date, place, cause, and burial site of the person who died. They name the spouse and parents of the deceased. Funeral home and informant details add leads for other searches. The informant’s name is often a close relative who can open new lines.
Marriage Records
Marriage records show date, county, ages, and birthplaces of bride and groom. They name witnesses and the officiant who performed the ceremony. A marriage license often gives parent names for both spouses. A bond can show who paid for the license and who approved the match.
Divorce Records
Divorce records list filing date, county, and grounds for divorce on the cover page. They may show property division and child custody terms. St. Louis County cases are filed with the Circuit Court. Older case files are held at the county archives.
Birth and Death Indexes
Indexes list name, year, and page number for each entry in a vital record volume. They help you find the right volume faster than guessing. Many indexes cover several counties at once in a statewide set. Digital indexes now let you search by name from your home.
Historical Vital Records
Historical records go back to the late 1800s for St. Louis County. Some earlier church records fill gaps before civil registration began in 1910. Family Bibles and cemetery readings also serve as vital records. These older sources often give more detail than later forms.
| Record Type | Years Often Covered | Key Facts Shown |
|---|---|---|
| Birth records | 1876 to present | Date, place, parents, doctor |
| Death records | 1876 to present | Date, cause, burial, spouse |
| Marriage records | 1876 to present | Date, ages, parents, witnesses |
| Divorce records | 1880s to present | Filing date, grounds, settlement |
Property and Estate Records
Property records show who owned land, when they bought it, and what they paid at the time. Estate records show how wealth passed after a death and who got each item. Together they form a record of family wealth and place over many decades. They also name children, spouses, and siblings who appear nowhere else.
Deed Records
Deed records show the transfer of land between people with a recorded date. Each deed names the grantor, grantee, date, and legal description of the property. Deeds often mention a spouse releasing dower rights. A chain of deeds can follow one family on one farm across several generations.
Property Ownership Records
Ownership chains follow a parcel across many deeds recorded over the years. They show who held the land at each decade and at what price. The Recorder of Deeds indexes work by both name and legal description. Grantor and grantee indexes help you trace a sale forward or backward.
Probate Cases
Probate cases settle a person’s estate after death under court supervision. They name heirs, debts, and assets held at the time of death. Case files often include the will, an inventory, and a final settlement. Probate packets can run from a few pages to several hundred pages.
Wills and Estates
Wills name heirs and the share each receives from the estate. They can name children not listed elsewhere in your research. An estate packet may include a will, an inventory, and receipts paid out. Witnesses on a will can also lead to other family lines.
Guardianship Records
Guardianship records cover minors and adults who could not manage their own affairs. They name the guardian and ward at the time of the case. They show how the ward’s property was handled and spent. These records are filed with the probate court.
Estate Inventories
Inventories list every item owned at death with an appraised value. They show household goods, livestock, and tools of the trade. Appraised values help you judge the family’s wealth at that time. Inventories also show where each item was located in the home.
Census and Community Records
Census records count people every ten years in the United States. Community records fill in the gaps between census years with other listings. They track schools, voters, and city residents for local use. Together they build a year-by-year picture of where a family lived.
Federal Census Records
Federal census records for St. Louis County begin in 1830 and run every ten years through 1950 under privacy rules. They name each household member, age, sex, race, and occupation in each household. Earlier years list only the head of household by name. Census records from 1850 onward list every member of the household by name.
State Census Records
Missouri took state censuses in some mid-decade years between federal counts. They help bridge the ten-year gaps with a fresh count. Some give agricultural and manufacturing details for the township. These records are held at the Missouri State Archives.
City Directories
City directories list residents, addresses, and jobs year by year in each town. They often appear between census years when no other list exists. They can confirm a move or a new occupation for an ancestor. A widow may appear under her own name with the word “widow” in the entry.
Voter Registration Records
Voter records show name, address, and party affiliation at the time of registration. They prove residency at a given date and place. They begin in different years by state and by county. Some early rolls list only men before women’s suffrage in 1920.
School and Community Records
School records list pupils, ages, parents, and home addresses on the page. Church records note baptisms, marriages, and burials on church paper. Fraternal and club rolls show community ties and dues. Each type adds a different kind of fact to the family story.
Historical Address Information
Old addresses help you match people across records at the same home. House numbers and street names changed over time in many towns. Sanborn maps and plat books show old property lines and building shapes. City directories can help you match a current address to an old one.
| Census Year | Details Recorded | Privacy Status |
|---|---|---|
| 1830 to 1840 | Head of household only | Public |
| 1850 to 1930 | Every household member named | Public |
| 1940 | Full household details with income | Public |
| 1950 | Full household details | Restricted (released 2022 onward) |
Military and Immigration Records
Military records cover service, draft, and pension files for each person who served. Immigration records cover arrival, citizenship, and naturalization papers at the port. They are key sources for ancestors who moved into or out of the county. They can also fill gaps when vital records are missing.
Military Service Records
Service records list enlistment, units served, and discharge date for each soldier. They cover wars from the Civil War forward through the modern era. Many service files are at the National Archives in Washington, D.C. Some compiled military service records are online through subscription sites.
Draft Registration Records
Draft cards list name, age, address, and a physical description on the front. They were filled out in 1917, 1918, and 1942 for the World Wars. They help locate men between census years when no other record exists. The cards can show an employer and a place of birth.
Pension Records
Pension files cover service-related injuries, widows, and old age on the application. They give marriage, death, and dependent details on later pages. Pension paperwork often includes affidavits and medical notes. These files can run well over one hundred pages per claim.
Immigration Records
Ship manifests list arrivals at American ports with full detail for each passenger. They name age, occupation, last residence, and the person who paid for passage. They also list family members who came along together. Manifests begin in 1820 at most major ports.
Naturalization Records
Naturalization papers show the path to citizenship over several filings. They include a declaration of intent and the final certificate at the end. Residents can also access official birth records to verify current details. They name the court, the date, and the witnesses on each paper. St. Louis courts held many of these records for the region.
Citizenship Records
Citizenship records prove legal status after naturalization was granted. They may give a birth date, birthplace, and arrival port on the form. Later documents confirm citizenship for children born abroad. A certificate of citizenship can also come through a parent.
Cemetery and Obituary Records
Cemetery and obituary records confirm death and burial for each ancestor. They often give next of kin, age, and cause of death on the page. Together they help close a person’s life record with a final note. They also point to living relatives who may hold family papers.
Cemetery Records
Cemetery records list name, birth, death, and plot location for each grave. Many local surveys are online through the library catalog. Plot maps show sections, rows, and grave numbers in the cemetery. A sexton record book can also show who paid for the plot.
Burial Information
Burial records give date, section, and often a tombstone transcription for each grave. They may note military service or fraternal membership on the stone. Family plots hold several generations together in one place. A church burial register can also serve as a burial record.
Obituaries
Obituaries name survivors, funeral home, and burial place in the notice. They often list parents, siblings, and children by name. Local newspapers printed them within a few days of death. Many older papers are now searchable through online databases.
Funeral Records
Funeral home records show date, place, age, and officiant for the service. They often include a copy of the obituary as filed. Some funeral homes released records decades after the service. A funeral record can confirm a middle name or a maiden name.
Memorial Records
Memorial cards and programs note the date and place of services for the family. They often show a photo and a short life sketch on the front. Family Bibles also serve as memorial records in many homes. A memorial record can lead to a final resting place.
Death-Related Historical Sources
Coroner reports, cemetery permits, and church burial logs add detail to a death. Death certificates sometimes attach delayed birth records for the same person. A coroner’s inquest can give an exact cause and witnesses. These records sit at the county or city level.
Building a Family History From Records
A family history grows from small clues that link across records over time. Each record adds a name, date, or place to the growing tree. The full picture comes from years of careful work and many sources. Each fact should have a source you can cite for future readers.
Identifying the First Known Ancestor
Start with the person you know most about in your family line. Confirm their birth, marriage, and death in two or more sources. Use this person as the anchor for your tree as you move back. A solid anchor prevents errors in later generations.
Connecting Parents and Children
Look for parents named on birth, marriage, death, and census records. The 1880 and later census lists each person’s relationship to the head of household. Probate records also link parents to children through inheritance. A baptismal entry can name both parents.
Establishing Family Relationships
Marriage records name both spouses and their parents on the page. Baptismal records list godparents, who were often relatives. Family Bibles list births, deaths, and marriages in one place. All three can confirm a relationship at the same time.
Tracking Residences Over Time
Census, city directory, and deed records show address changes across the years. Compare entries year by year for the same person. A move of a few miles can change the county or the state line. Land records can show the exact parcel a family lived on.
Following Name Changes
Women often took a husband’s surname at marriage under common law. Some families shortened or anglicized foreign names at the port. Court records show legal name changes for adults when filed. A child’s death record can show the mother’s maiden name.
Organizing Evidence by Generation
Group records by parent, child, and grandchild in clear folders. Use a folder or digital file for each person in your tree. A timeline shows gaps that need more research. A source list at the back of each folder keeps citations clear.
Genealogy Record Verification
Verification means comparing records to make sure they agree on the same facts. A single record can contain errors from clerks and informants. Two or more records that match build confidence in a fact. A fact with one source is a clue, not proof.
Comparing Independent Sources
Use records created by different offices for the same fact. A birth date from a birth certificate and a baptismal record both count. They should agree within a few days of each other. Two matching sources raise the trust in the fact.
Confirming Names and Dates
Check the spelling of names against each record at every step. Dates may differ because of recording delays or memory errors. Look for a pattern across multiple sources on the same fact. The pattern points to the truth.
Checking Locations
Make sure the town, county, and state existed at the time of the record. Some place names changed across the decades. Township maps from the same era help with location checks. A place that did not exist proves the record is wrong.
Resolving Conflicting Records
When records disagree, weigh each source by who created it. Original records beat copied records in most cases. Closer in time usually means more accurate on a fact. The most reliable source wins the conflict.
Distinguishing Individuals With Similar Names
Two people of the same name may live in the same county at the same time. Use age, spouse, occupation, and address to tell them apart. Build a profile that fits only one person on the page. A census neighbor can also help separate two families.
Evaluating Record Reliability
Reliable records have an author, a date, and a place of creation on the page. Originals beat copies and abstracts in most cases. Witness signatures add weight to a record’s facts. The source itself should always be checked.

Genealogy Research Problems
Every search hits a wall at some point in the work. Knowing the common problems helps you plan a fix for each one. A second look at the same records often solves the issue. A fresh set of eyes from a relative or a helper can also break the wall.
Ancestor Not Found
An ancestor may not show up because the name is spelled wrong on the record. Try surname variants and check both parents’ surnames in each search. Search nearby counties where the family may have moved. A second county often holds the missing ancestor.
Variant Name Spellings
Clerks spelled names the way they sounded to the ear. Andrew might be Anders or Andreas on different pages. Phonetic searches pick up most variants of a name. Wildcard searches can also help with a missing letter.
Missing Records
A courthouse fire, flood, or simple loss can destroy records over time. Substitute records from churches, schools, or newspapers can fill the gap. Tax lists and land records can sometimes fill a vital records gap. A neighbor’s family may hold the lost fact.
Incomplete Records
Some records list only the head of household by name on the page. Age may be rounded to the nearest five or ten years by clerks. Treat each fact as a clue, not a final answer. A second record can fill the missing field.
Wrong County or Jurisdiction
County lines changed over time in the St. Louis area. A town once in St. Louis County may be in St. Louis City or Jefferson County today. Old maps show the right line for the year of the record. A boundary change can hide your ancestor.
Conflicting Information
Two records may give different dates or places for the same fact. Note both, then look for a third record that confirms one of them. Weigh each source by who created it and how close in time. The most reliable source should win the conflict.
Records That Are Not Yet Digitized
Some records are still in binders or on microfilm at the library. They can be viewed at the library or through a paid lookup service. A staff search can save you time on a long project. Ask the librarian what is on the next digitization list.
Genealogy Records and Related Research
Genealogy records overlap with other record types in many ways. Knowing the difference helps you pick the right source for each question. Each type of record answers a different question about the same person. The right source saves hours of search time.
Genealogy Records vs. Vital Records
Vital records are one kind of genealogy record on a single page. They cover birth, death, marriage, and divorce events. Genealogy records also include deeds, censuses, and many other sources. Vital records give dates, other records give the full picture.
Genealogy Records vs. Family Trees
Family trees are built from genealogy records over time. A tree is a summary, the records are the proof behind each fact. Always cite the record behind each fact on the tree. A tree without sources is just a guess.
Genealogy Records vs. Historical Archives
Historical archives hold old papers, photos, and manuscripts on a topic. They add color to a family story with personal detail. They do not replace the basic vital, census, and deed records. They fill in the life between the big events.
Genealogy Records vs. Public Records
Public records are any record a government office creates and keeps. They include deeds, court files, and meeting minutes. Many public records serve genealogy research on the same facts. Other public records have nothing to do with family history.
Genealogy Records vs. Census Records
Census records are one type of genealogy record on a single page. They give a household snapshot every ten years for the country. Vital, deed, and probate records cover events in between. All three work together to build a full picture.
