How to Discover Your American Ancestry

Genealogy is a fascinating field that allows us to discover our ancestry and the various ethnic groups that make up our DNA. In the United States, there are numerous ancestry groups that are commonly found, such as those of European, African, and Native American descent. Here are some ways to discover your ancestry groups in the U.S.

Census Records

Census records are a valuable resource for discovering your ancestry groups in the U.S. These records were taken every 10 years, starting in 1790, and provide information on the population of the country. You can search census records online or visit your local library or historical society to access them. Census records can reveal information such as your ancestors' birthplace, occupation, and ethnicity.

Church Records

Church records can provide valuable information on your ancestors' religious affiliation, baptism, marriage, and burial. These records can also reveal information on your ancestors' immigration and naturalization status. You can access church records online or visit the church archives to search for information.

DNA Testing

DNA testing is a popular way to discover your ancestry groups. There are several DNA testing companies that offer this service, such as AncestryDNA, 23andMe, and FamilyTreeDNA. These tests can reveal your ethnicity estimate, which will show the percentage of your DNA that comes from different regions of the world. For example, you may discover that you have Irish, German, and Italian ancestry.

Family History

Talking to your relatives and researching your family history can also provide insight into your ancestry groups. Family stories, photographs, and documents can reveal information on your ancestors' ethnicity, religion, and traditions. You can also use genealogy websites such as Ancestry.com and FamilySearch.org to create your family tree and connect with other relatives.

Immigration Records

Immigration records can provide valuable information on your ancestors' country of origin and their journey to the U.S. There are several online databases that offer access to immigration records, such as Ellis Island and Castle Garden. These records can also provide information on your ancestors' age, occupations, and family members.

Land Records

Land records can provide information on your ancestors' land ownership and property transactions. These records can also reveal information on your ancestors' occupation and economic status. You can access land records online or visit the county courthouse to search for information.

Military Records

Military records can provide information on your ancestors' service in the U.S. military and their involvement in wars and conflicts. These records can also provide information on your ancestors' rank, unit, and medals. You can access military records online or visit the National Archives to search for information.

NOTES: Ancestry is a broad concept that can mean different things to different people. The ancestry groups listed on this table were self-identified. The Census Bureau defines ancestry as a person's ethnic origin, heritage, descent, or roots, which may reflect their place of birth, place of birth of parents or ancestors, and ethnic identities that have evolved within the United States. Many respondents listed more than one area of ancestry; the sum of the persons reporting the ancestry is greater than the total. Overall, about 500 different ancestries were reported during Census 2000. The 2015 Census did not include questions explicitly about ancestry, but other government bodies record population by race.

1. Group may encompass several ancestries not listed separately

2. Data is from American Community Survey 5-year estimates 2015-2020, 2010-2014.
