Corson Surname DNA Project Newsletter July 2006

Hello everyone,
In the past month, one participant received his test results. My recruitment efforts have slowed since May, but should pick up again in September. In the meantime, do any of you have a male Corson/Colson/Courson/Corsa/Vroom/etc. relative who doesn't know about the project yet? Perhaps he would be interested in participating. I'll be happy to answer any questions you or he may have.

30 participants, 29 test results reported
Separate families: 13 (1 set of eight participants, 1 set of four, 2 sets of three, 2 sets of two, 7 unmatched)
Families in each haplogroup: 9 in R1b; 1 each in E3b, I1a, I1b2a, and J2


DIVISION I (New England) - 8 participants, 8 results

Participant #30, who traces his descent from James Collson (c.1750-1825), a younger son of Samuel's second son, Hatevil (1714-1798), received his results. His genetic signature matched the ancestral Division I signature on 42 of 43 markers tested, corroborating his documented male-line descent. He differed on marker DYS 464c (a value of 16 instead of 15). Because he did not have the same mutations as his sixth cousin, once removed, Participant #12, these results suggest that Hatevil, their most-recent common ancestor, carried the ancestral genetic signature. Thus, in the 7-8 generations that separate them from Hatevil, each family line independently generated the 1-2 mutations observed in each.


DIVISION II (Sussex Co., NJ) - 4 participants, 3 results - More participants from this Division are welcome; their results could help strengthen the assertion that we know progenitor Jan Corszen's (d. 1703) genetic signature.

DIVISION III (Staten Island, NY) - 6 participants and results - We are still looking for participants from the following lines: male-line descendants of (1) Hendrick Vroom's (1683-1769) brothers Cornelius (b. 1677) or Alfred, and (2) Benjamin Corssen's brothers Jacob (1681-1742) or Christian (1676-aft. 1764). We're also looking for other descendants of William DeCoursey (bef. 1720-1788) to participate. Until then, we won't know if the Corson, Vroom, or DeCoursey genetic signature (if any of them) represents that carried by progenitor Cors Pieterszen (1612-1655).

DIVISION IV (Cape May Co., NJ) - 4 participants and results - Now that we have identified the ancestral genetic signature for this Division, we are searching for genetic matches in Europe that might indicate progenitor Carsten Jansen's (1634-c.1697) region of origin. We welcome other participants from this Division.

DIVISION Va (Dumfriesshire, Scotland) - 1 participant and result - We're looking for another male-line descendant from this family so we can estimate its ancestral genetic signature.

DIVISION VII (Hunterdon Co., NJ) - 2 participants and results - Now that have identified the ancestral genetic signature of progenitor Jacob Corson (c.1755-bef.1822), we're looking for genetic matches that could indicate where Jacob's male-line ancestors came from. Other participants from this Division are welcome.

DIVISION VIII (Colsons not derived from Corsons) - 1 participant and result - The current participant descends from Adam Cols(t)on of Massachusetts, born ca. 1660. We welcome participation by those descended from him or other Colson progenitors.

DIVISIONS VI, IX, and XIII - no participants - We still wish to recruit descendants of Daniel Corson (1763-1849), who moved from Sussex County, NJ to Ontario, Canada. We're also searching for participants with ancestors from European Corson / Corsan / Courson / Curzon / Korson families.

UNCONNECTED - 4 participants and results - Three Corson participants and one Courson participant remain unconnected to other participants in the project.


At least $315 remains in the subsidy fund to reimburse all or a portion of the test costs for four participants from particular family lines in Divisions III, X, and XIII. You can see additional details at the project website:
