If you’d like to learn more about where you came from, I mean further back than any paper trail will lead you, then opt in for ancestry DNA testing. This is exactly what I did through a company called 23andme.
According to their website, you can “Trace your lineage back 10,000 years and discover your history from over 750 maternal lineages and over 500 paternal lineages”. Just what I need to supplement my already extensive family tree.
I’ve been working on my family tree for years using Ancestry.com and FamilySearch.org. It currently goes back as far as the 1500’s on some branches, but to watch that extend back thousands of years will be extremely satisfying.
