My 7th GG Christopher Calvert was transported to Accomack Co, VA in 1636. y-DNA shows that my family has gone under the surnames Calvert, Colvard, and Colbert. Benjamin Colvard/Colbert Jr., who worked as a carpenter at Monticello, is a descendant of Christopher. Ben, Jr. is also the father of Betty Brown's children under the Colbert name. Betty Brown was dau. of Elizabeth Hemings and half-sister of Sally Hemings. Family Tree DNA and Ancestry.com confirm I am related to Hemings family. DNA testing at Ancestry.com and at Family Tree DNA that is managed by CeCe Moore also confirms I am related.
