We have about 50 men and women who have tested at 23andMe through our Vick and Allied Families DNA Project. 23andMe tests single nucleotide polymorphisms (SNPs) from all 23 pairs of our chromosomes and our mitochondrial DNA. Twelve of the men in our 23andMe project are also members of our Vick Y-DNA Surname Project. The members of our Y-DNA surname project have had Y-DNA short tandem repeat (STR) tests. These Y-STR tests are the “gold standard” for those who want to explore just their patrilineal line (i.e. their father’s, father’s…line). Eleven of the men who are in both projects match the Y-DNA signature of Joseph Vick of Isle of Wight Co., VA. Joseph was born about 1640-1650. The twelfth may be descended from a Vick female.
To understand one-way we might use the 23andMe data in reconstructing our Vick family tree, a few of us have begun to share screenshots of our Relative Finder match lists and our Family Inheritance screens. Ralph Lewis Vick is one of the men who had both types of testing. Ralph’s Y-STR results matched the Y-STR signature of Joseph Vick of Lower Parish, Isle of Wight Co., VA.
Jesse Mayfield is Ralph’s second cousin. Their most recent common ancestors are Benjamin Henry Vick and his wife Mary Ann Elizabeth Turner. Jesse has also been Y-STR tested. However, since Jesse is not a patrilineal descendant of his Vick ancestor he cannot use his Y-STR results to support his VICK ancestry. His Y-DNA came from his father who is not a Vick descendant. Both Ralph and Jesse have been tested by 23andMe. Using their SNP results, 23andMe’s Relative Finder correctly predicted that Ralph and Jesse were second cousins.
Because of their match at 23andMe we have strong support that Jesse’s pedigree is correct and that he is also a descendant of Joseph Vick. Before 23andMe’s Relative Finder, Jesse could only ask his closest male VICK cousin to take a Y-STR test and then argue that his cousin’s results should also be extended to him. Now because of Relative Finder Jesse can show that his second cousin is his second cousin and that Jesse’s own DNA supports his Vick ancestry.
I love the way results from the two projects help us in our efforts to reconstruct our Vick family tree. I cannot wait to apply this technique to other non-patrilineal Vick close cousins of other men who have or will test in both projects.
