I wondered what records I might be missing out on in my research, so I decided to ask the OpenAI ChatGPT5 AI tool. My prompt was: "Please define and provide a description of 20 record types that every genealogist should search for when researching each ancestor or relative."
(Gemini Notebook Infographic - 20 record types for genealogists)
The OpenAI ChatGPT5 response was:
No single ancestor will appear in every type of record, but experienced genealogists develop a habit of searching for the same broad set of records for each person. Even a record that is not found can be valuable evidence, helping establish where a person was not living or suggesting that records were lost or never created.
The Record Types:
Here are 20 of the most important record types that every genealogist should search for.
1. Birth Records -- Birth certificates, registrations, delayed birth records, and birth returns often provide the person's full name, date and place of birth, parents' names, occupations, residence, and informant. These are among the strongest records for establishing parent-child relationships.2. Baptism or Christening Records -- Church records may predate civil registration and often identify parents, sponsors (who may be relatives), parish of residence, and occasionally grandparents. Particularly valuable before civil birth records existed.
3. Marriage Records -- Marriage licenses, certificates, bonds, banns, and church registers identify spouses, ages, residences, occupations, parents, previous marriages, witnesses, and officiants. Witnesses frequently reveal extended family members.
4. Divorce Records -- Divorce petitions, decrees, and court files can reveal marriage details, children, residences, financial circumstances, and family disputes. These often contain extensive testimony unavailable elsewhere.
5. Death Records -- Death certificates provide death date and place, cause of death, burial information, parents' names, spouse, occupation, residence, and informant. Accuracy depends upon the informant's knowledge.
6. Burial, Cemetery, and Funeral Records -- Gravestones, cemetery registers, plot purchases, sexton records, and funeral home files often identify family members buried together, military service, religious affiliation, and next of kin.
7. Census Records -- Population schedules provide names, ages, occupations, birthplaces, immigration status, relationships, education, and property ownership. Comparing multiple census years documents family movement and changes over time.
8. Probate Records -- Wills, estate administrations, inventories, guardianships, and distributions identify heirs, spouses, children, siblings, property, and family relationships. Probate records often provide the strongest direct evidence of family connections.
9. Land and Property Records -- Deeds, mortgages, land patents, grants, and tax maps document residence, property ownership, neighbors, migration, and family transfers. Family members often bought or sold land to one another.
10. Tax Records -- Annual tax rolls can place an ancestor in a location between census years, estimate wealth, identify land ownership, and help distinguish men of the same name. They are especially valuable where census records are missing.
11. Military Records -- Draft registrations, service records, pension files, bounty land applications, and discharge papers may include birth information, family members, physical descriptions, residences, and affidavits from relatives and neighbors.
12. Immigration and Naturalization Records -- Passenger lists, border crossings, passport applications, declarations of intention, and naturalization petitions document migration, birthplace, family members, previous residence, and arrival information.
13. City Directories -- Published annually in many cities, directories identify residences, occupations, employers, spouses, and business advertisements. They help track families between census years and reveal when individuals moved or died.
14. Newspapers -- Obituaries, marriage announcements, birth notices, legal notices, business advertisements, social columns, and local news often provide details unavailable in official records and add personality to an ancestor's life story.
15. Church Records -- Membership rolls, confirmations, communions, marriages, funerals, transfers, and meeting minutes often identify families over many years and reveal religious affiliations and community involvement.
16. School Records -- Attendance registers, report cards, yearbooks, alumni directories, commencement programs, and school newspapers document education, residences, extracurricular activities, and photographs.
17. Court Records -- Civil lawsuits, criminal proceedings, guardianships, adoptions, apprenticeships, and other court actions often contain detailed testimony, relationships, financial information, and residence data.
18. Employment and Occupational Records -- Personnel files, company newsletters, pension records, union records, professional licenses, and business directories document careers, promotions, addresses, education, and retirement.
19. Family Records -- Family Bibles, letters, diaries, journals, photographs, scrapbooks, autograph books, memoirs, recipe books, and oral histories provide personal details, relationships, traditions, and events often found nowhere else.
20. Published Genealogies and Local Histories -- County histories, town histories, family genealogies, biographical compilations, and historical society publications can provide clues, context, and references to original sources. They should always be verified with primary records.
Why Search All Twenty?
Every record type answers different genealogical questions:
Who? Birth, baptism, marriage, probate, and family records identify relationships.
When? Vital records, census schedules, and newspapers establish timelines.
Where? Land, tax, census, city directories, and church records document residences and migration.
What? Military, employment, school, and court records reveal occupations, education, and life events.
Why? Probate, divorce, newspapers, court records, and personal papers explain the circumstances behind family decisions and significant events.
A Practical Research Strategy
For every direct ancestor or close relative, create a checklist of these twenty record categories. As you research each person, record:
Whether you searched for each record type.
Where you searched (repositories and websites).
What you found—or did not find.
The source citation for every record examined.
Ideas for future research when records are missing.
Summary
This systematic approach helps ensure that no major source category is overlooked. It also aligns well with the principles of the Genealogical Proof Standard (GPS) by encouraging a reasonably exhaustive search, careful source citation, thorough analysis, and soundly reasoned conclusions. For genealogists working on complex family lines, this checklist often becomes the backbone of an effective research log and greatly increases the likelihood of discovering new evidence.

For experienced researchers like you, maintaining a research checklist of 60–100 record types can be invaluable. As you work through each ancestor in your RootsMagic database, you can systematically record which categories have been searched, where they were searched, what was found, and what remains to be investigated. This kind of comprehensive checklist supports thorough, repeatable research and is an excellent foundation for meeting the Genealogical Proof Standard while ensuring no major source category is overlooked.

A Google Gemini Notebook Video Overview of the Top 20 is below and on my YouTube channel shortly:
That is a fairly succinct Top 20 list and set of descriptions. I have pursued most of those records but not school records, court records, or employment records to any degree.
The list of 40 more record types is more esoteric and specialized. I've used some of them, like Social Security Applications, Voter Registrations, Passport Applications, and Homestead records, mainly because they appear in Record Hints and Searches.
What other record types can you think of?
