Mary Waters Taylor was born in Kentucky 6 days before portions of Green County, KY were made into Adair County, KY of December 11, 1801. Adair County Kentucky was named after Major General, Revolutionary & Indian War veteran, Kentucky constitutional convention delegate, & Kentucky House of Representatives member John Adair (1757 SC-1840), with whom the Taylor family was acquainted.
Mary's parents were George Taylor (1761 Albemarle Co, VA - Schuyler Co, IL 1834) & Ann Waters (1765-1836).
Her grandfather Zachariah Taylor (1739-1794) served in the Revolutionary War.
President Zachary Taylor's great great great great grandfather Thomas Taylor (1574-1618) was also her father's great great great great grandfather, so she was the President's 5th cousin once removed.
Genealogists think the wife of Thomas Taylor (1574-1618), named Margaret Swinderly (1578-1672) was born in Copenhagen, Denmark.

There are 100 genetically distinct subfamilies of R-M269 in the Taylor project, as well as same R1a men (R-M269 is R1b), & haplogroups A, E, G, I, J & Q. https://www.familytreedna.com/public/taylorfamilygenes/default.aspx?section=ycolorized
