Step 1. Find out everything possible from living relatives and their family records.[edit | edit source]

Every good genealogy project starts with finding all the clues that can be gathered from living relatives — both from their memories and from documents or memorabilia in their homes.

What information can relatives help with??[edit | edit source]

In order to extend research on ancestors, look for names, dates, and places. Any information about when and where a relative lived is a clue to a new record search. Be sure to ask questions that lead to that information, including about their occupations, military service, or associations with others, such as fraternal organizations. See also:

What documents can relatives help with?[edit | edit source]

  • Announcements of births, weddings,
    and anniversaries
  • Baby and wedding books
  • Certificates
  • Deeds, and property records
  • Family Bibles
  • Family reunion notices and records
  • Fraternal or society records
  • Insurance policies
  • Journals and diaries
  • Letters and cards
  • Licenses (business, marriage,
    fishing, driving)
  • Naturalization documents
  • Newspaper clippings and obituaries
  • Medical records
  • Military service and pension documents
  • Occupational awards
  • Passports
  • Personal histories and biographies
  • Photograph albums
  • Printed Notices and Announcements
  • Programs (graduation, award ceremonies, funerals)
  • School records
  • Scrapbooks
  • Wills and trusts

Step 2. Find ancestors in every possible census record, 1900-1940, online.[edit | edit source]

A census is a count and description of the population of a country, state, county, or city for a given date. A census took a "snapshot" of a family on a certain day. For each person living in a household you might find (depending on the year) their name, age, birthplace, relationship to head of household, place of birth for father and mother, citizenship status, year of immigration, mother of how many children and number of children living, native language, and whether they were a veteran of the military.

Using the clues in home records to lead to census record searches.[edit | edit source]

In the obituary on the left, notice that

  • Herman G. Gauger died in 1975 at age 89, giving him a birth year of 1885-1886.
  • Although he was born in Ohio, it appears that he lived in California for most of his life.

The first goal would be to gather data about his immediate family (wife and children) in census records of California for 1920, 1930, 1940, and 1950.

Look for ancestors in as many censuses as possible. Use the clues from each census for hints where to find families in both earlier and later census records.[edit | edit source]




For more information, see California Census and United States Census.

Step 3: Find birth, marriage, and death certificates for ancestors and their children.[edit | edit source]

States, counties, or (even towns in some states) recorded births, marriages, and deaths.

  • In addition to the child's name, birth date, and place of birth, a birth certificate may give the birthplaces of the parents, their ages, and occupations. *A marriage certificate might list the parents of the bride and groom.
  • A death certificate may give the person's birth date and place, parents' names and birthplaces, and spouse's name.


Using census clues to lead to a birth certificate.[edit | edit source]

Census information gives approximate birth years and probable birth places, and that information leads to finding important birth records. In addition to basic birth date and place, a birth certificate can give age, birthplace, occupation, etc. about the parents.

The examples shown above are index entries. That means for each of them an actual, original, full certificate exists. It is highly advisable to order the original certificate. It will contain many details not given in the index. Instructions are given below on obtaining the original certificate.

Using census clues to lead to a marriage certificate.[edit | edit source]

Finding marriage records can:

  • establish the full identity of the wife, with her maiden name and possible birth details.
  • find the names of the parents of the bride and groom.

Using census clues to lead to a death certificate.[edit | edit source]

Moving forward in time, older generations stop showing up in the census. That is a clue that they probably died in the last 10 years. The death certificate is important because of all the possible secondary data beyond just the date and place of death:

  • birth date and place of the deceased
  • maiden name of the wife
  • names of the deceased's parents
  • birth places of the deceased's parents.

Gather as many birth, marriage, and death records as possible.[edit | edit source]


How to Find the Records[edit | edit source]

There are basically three ways to find these indexes or full original certificates:


Online databases, usually indexes, with some images[edit | edit source]

Also, see How to Find California Death Records

Records at the County Courthouse.[edit | edit source]

These records were originally created by county clerks, and then copies were sent to the state. County clerks can be willing to help find all the birth records for one family or perform other searches that the state would not do. To contact county clerks by e-mail or telephone, go to the Wiki article for each county. Links to the county Wiki articles are found at the end of this page or by clicking here: California Counties.

Order Certificates from California Vital Records Department.[edit | edit source]

Almost always the full original certificate will contain information not contained in the index. Although it costs money, consider sending for the full original certificates, particularly for direct line ancestors (grandparents, great-grandparents, etc).


For more information on birth, marriage, and death records in California, see How to Find California Birth Records, How to Find California Marriage Records, and How to Find California Death Records.

Step 4: Try to find additional details about ancestors in obituaries, cemetery records, and Social Security records online.[edit | edit source]

There are additional record collections available, based upon a person's death: obituaries, cemetery records, and Social Security records. These are a great source for more details about a person. Here are some examples; notice the level of details.

Obituaries[edit | edit source]

Cemeteries[edit | edit source]

U.S. Social Security Death Index and Social Security Applications and Claims Index, 1936-2007[edit | edit source]

  • The U.S. Social Security program began in 1935 but most deaths recorded in the index happened after 1962.
  • The Social Security Death index includes those who had a Social Security number and/or applied for benefits.
  • You can search these records online at
*1935-2014 U.S., Social Security Death Index, 1935-2014 at Ancestry — index ($)
*1936-2007 U.S., Social Security Applications and Claims Index, 1936-2007 at Ancestry, Picks up where the Social Security Death Index (SSDI) leaves off by providing information filed in the application or claims process — index ($)
  • If you find an ancestor in the SSDI index, you can order a copy of their original Social Security application (SS-5). If you can prove the individual has died (by sending an obituary or copy of their cemetery headstone), the application will also give the deceased's parents' names, if listed.

For more information, see California Obituaries and California Cemeteries.

Step 5: Search military records: World War I and II draft cards.[edit | edit source]

There are many different types of military records: draft records, enlistment records, service records, pension records, etc. Information in military records can vary from a simple lists of name, age, and residence, to more detailed records including name, residence, age, occupation, marital status, birthplace, physical description, number of dependents, pensions received, disabled veterans, needy veterans, widows or orphans of veterans, and other information.

Search the World War I and World War II Draft Collections for male relatives.[edit | edit source]




For more information and additional collections, see California Military Records.

Step 6: Look for church records.[edit | edit source]

Church records function as vital records.

  • An infant christening or baptism record documents a birth.
  • Many, if not most, people are married in a church, and then a record is created by the minister.
  • Likewise, ministers presided over funerals, then creating a burial record, which documents a death.

Church records are particularly helpful prior to the advent of civil registration.

Step 7: Search for online wills and probate packets.[edit | edit source]

  • County probate records include probate proceedings, petitions, affidavits, orders for sales, reports of sales, administrators' and executors' bonds, guardianship papers, wills, and letters of administration.
  • In a will book, usually just a transcription of the will is recorded. But all of these other records are kept in a probate packet.
  • Administrations are probate proceedings that handled an estate if no known will existed.

Search these indexes and images for probate records.[edit | edit source]



Probate Information in County Wiki Articles[edit | edit source]

Each California county Research Wiki page lists additional probate sources, including where to write for records: California Counties


For more information, see California Probate Records and United States Probate Records.

Step 8: If any ancestor was an immigrant, search immigration and naturalization records online.[edit | edit source]

The census records may show that an ancestor was born in another country. It will be necessary to try to find the town or city they were born in to continue research in the country of origin. Searches of immigration records (usually passenger lists) and naturalization (citizenship) records would be the next step.

Step 9: Use other FamilySearch tools.[edit | edit source]

Historical Images[edit | edit source]

Records collected and digitized by FamilySearch can all be found through their Historical Images feature.


California Online Genealogy Records[edit | edit source]

Search any other online records listed in California Online Genealogy Records. The steps given here are intended to list record sources which can most efficiently identify descendants. Many other online records which might or might not mention descendants are listed in the California Online Genealogy Records page, including immigration records, land records, military records, newspapers, and probate records, and others. These can be records that cover a smaller group within the population, such as men who served in the military, etc.



Step 10: Study the Research Wiki pages for any county in California.[edit | edit source]

This article focused more on California state or state-wide records. There is a separate Wiki article for each county in California. These articles give information, office addresses, and links to county records.
