Genetic genealogy is the use of DNA testing in combination with traditional genealogical and historical records to determine family relationships.
cM = Centimorgan, a way of measuring a unit of DNA that has been passed down from ancestors. From Ancestry.com: When two people have a DNA match, it means they inherited DNA from one or more recent common ancestors. The length of DNA they have in common is estimated in centimorgans (cM). The higher the number, the closer the relationship.
Note: Ancestry.com adds a generic, vague, and sometimes inaccurate label to each set of DNA relatives, such as “2nd cousin” or “4th-6th cousin” when the match is actually a half 1st cousin, or great-aunt, or 3rd cousin, 1 times removed, etc. There is a little “i” for information on the full range of relationship possibilities next to each DNA match, which is much more accurate.
