DUKE
(DUKES, Duc, LEDUC, DuGuŽ AND OTher VARIANTS)
GENEALOGICAL
DNA PROJECT
The Duke family DNA project is making possible the
identification of separate family groups bearing the surname ÒDukeÓ through
distinctive yDNA patterns. Families with similar and related surnames (Dukes,
Duc, Dugue, DuGuŽ, or other variants) are also included in this surname group.
The study also allows us to clarify the internal histories of these family
groups.
The Duke surname DNA study is being conducted by Family Tree
DNA, with analysis of samples at the University of Arizona.
Several major Duke family groups
have been identified:
- Group
1: One individual is definitely a descendant of Joseph Duke of
Orangeburg County, SC, and documents indicate that the other test subject
is a descendant of Joseph or a close relative of his. Joseph Duke appears
in the Orangeburg parish records in 1750. SNP subclade testing has placed
this family in haplogroup J2f (J2a1a in the Sengupta et al 2006 nomenclature), which probably arose from a
mutation in the vicinity of the Caucasus and spread through maritime
contact with areas on the coasts of Crete, western Anatolia, Italy, and
Spain.

- Group
2: This large family includes descendants of 17th century Isle of
Wight Co VA settler John Duke. Their haplogroup is I, the second most
common among persons of European descent.

- Group 3: Another group of
three tested individuals is associated with the family of Mordecai Duke.
This family group falls within haplogroup I.
- Group 4: This group includes
individuals from eastern Henrico County, VA, from Kentucky via Maryland,
and also individuals believed to be descendants of Capt. Henry Duke of
Prince George Co. VA, through his son John Taylor Duke. One test subject
is from a line that includes a Mastin/Maston/Marston Duke in Henrico Co,
VA, a name that is documented in the family of Col. Henry Duke. This group
also includes a Duke family descended from John Duke b. 1757 Surrey,
England, who may or may not have an early pre-immigration connection with
the American family in this group. The group also includes three
descendants of Squire Staggs Ashley, believed to be a Duke descendant who
took the Ashley name.
