Last year I sent samples for the Ancestry.com DNA test in hopes of matching to other Sanders lines but without success. I may not know how to use the results properly but so far all they have done is to tell me how I am related to people in my SANDERS BRUNSON Family Tree, primarily my mother's lines. Very disappointing.
You must have paid to have a complete DNA test conducted on yourself. All I understand from my $10 test is that 95% of my ancestry comes from the UK.
There are a lot of similarities in the names of your family and mine. My G G Grandmother was Susan BROWN born 1832 NC and my G Grandfather was George Thomas SANDERS born 1853 TN. Our known line migrated from Lincoln County, Tennessee to Shelby and Tipton County Tennessee to Mississippi County Arkansas.
