Project Results and Discussion Lineage III Andrew Dorsey Line Table III-1 below summarizes and compares the haplotypes of a group of Dorseys who trace their origins to individuals living in Rowan, Lincoln, and Burke Counties in western North Carolina in the late 1700’s. A number of records cluster these individuals around Andrew Dorsey who moved from Baltimore County, MD to Rowan County in 1766.1 The first line of the table is the haplotype of a proven descendent of Andrew Dorsey’s grandson Elisha (son of Andrew's proven son Endymion2,3). The next line, which matches that one at all 25 markers tested in common, is from a descendent of Dimmon Dorsey of North Carolina and Tennessee.4 That perfect match, the appearance of Dimmon Dorsey in several public records with other known members of Elisha Dorsey’s family, and the use of the unusual name Dimmon (for Endymion) in both lines insure these two share a close common ancestor. Though not proven directly, it is believed that Dimmon was another son of Endymion Dorsey and thus a brother to Elisha. Confirmation of a close relationship is found in the uniqueness of the DNA signatures of these two individuals. Though they share many of the values of the Western Atlantic Modal Haplotype5, they also share unusual values for four markers in this 25 marker set. They have no exact or near matches outside of the Dorsey surname in the Family Tree DNA database6, no matches in the worldwide population sample of 24,189 in the www.yhrd.org database7, and no matches in the Sorenson Molecular Genealogy database.8 Frequency values for each of their markers are reported in the last line of Table III-1.9 Particularly rare is the value of 32 for DYS389ii. Other unusual values occur at DYS#’s 390, 459b, and 447. This is truly an unusual haplotype. Along with supporting traditional genealogical records, it leaves no chance that this is a spurious match of unrelated people who happen to share the Dorsey surname (or one of its several variants) and have roots in the same geographical place at the same time.
