Our Families:
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 J2a4b* (previously known as J2f, J2a1a in the Sengupta et al 2006 nomenclature, or J2a2), 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.

the Group
1 Web Site.
- 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.
More
Information is available at Group 2 Web Site.

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. The group also includes three descendants
of Squire Staggs Ashley, believed to be a Duke descendant who took the
Ashley name.

5: This group includes several families that emigrated from the South
Carolina Midlands (Fairfield, Kershaw, Richland and Lexington counties) to
Alabama and Mississippi. It also includes the family of John Duke of
Lancaster Co SC, whose sons John and Moses Duke went on to Barnwell Co SC,
John later immigrating to Tatnall Co GA. This group falls within

Ancestors charges £50 for access to their database and they provide no
information on the size of the database or information available, so we havenÕt
taken that approach. Since you are here using our data, you obviously believe
in free access, and we hope that you will let us know if you match any of our
