Corson Surname DNA Project Newsletter - March 2006

Hello everyone,

Since last month's report, four participants signed up and two, from Divisions I and VII, received test results. The news for the latter is particularly significant.



26 participants, 23 test results reported

Separate family lines: 12 (1 set of four participants, 3 sets of three, 2 sets of two, 6 unmatched)

Family line haplogroups: 8 in R1b; 1 each in E3b, I1a, I1c, and J2

Average time for lab to process a DNA sample: 12 days

Average time from sign-up to receipt of test results: 35 days


DIVISION I (New England) - 5 participants, 4 results

A Colson participant (#25) who believes that he descends from Samuel Colson (1719-1810) (Div. I-D), grandson of progenitor Cornelius Cursonwhit (c.1660-c.1710), recently joined. Documentation for his male-line ancestry remains solid up to John B. Colson (c.1802-aft.1870), who was born in Cherryfield, Maine and died in Menard Co., Illinois. Samuel Colson helped settle Cherryfield around 1756, and one of his sons, Isaac (1790-1854), moved from Cherryfield to Illinois in 1819. Isaac lived in Menard County, Illinois in 1830. Thus, we believe that John B. Colson is related to Isaac Colson, but do not have documentation to determine whether, or how, they were related. This participant's results, then, could confirm that John B. Colson indeed belongs to Division I.

The Corson participant (#22) who documents descent from Zebulon Corson's (1712-1786) (Div. I-A) son Aaron (c.1741-c.1812) received his results this week. His results match the genetic signature estimated for Division I on all 43 markers, corroborating his documented male-line genealogy. To date, descendants of three of Zebulon's four sons have had DNA tested.

DIVISION IV (Cape May Co., NJ) - 5 participants, 4 results

A Corson participant (#26) who documents descent from John Corson (c.1660-1728) via his great-grandson Joel Corson (d. 1823) recently joined. His results could resolve the uncertainty about progenitor Carsten Jansen's (1634-c.1697) genetic signature.

DIVISION Va (Dumfriesshire, Scotland) - 1 participant

A Corson participant (#23) who documents descent from William Corson (c.1735-1802) recently joined. His male-line ancestors lived in Dumfries, Scotland for several generations before moving to Glascow, Scotland. A few generations later, they moved to North Ryde, New South Wales, Australia.

DIVISION VII (Hunterdon Co., NJ) - 2 participants and results

A Corson participant (#24) who documents descent from progenitor Jacob Corson's (c.1755-c.1825) son Jacob Corson, Jr. (1801-1875) both joined and received his results. His genetic signature matches that of the other participant from Division VII on all 43 markers tested. This confirms both participants' male-line genealogies and establishes the genetic signature of Jacob Corson himself. We now can deduce that he did not descend in a direct male-line from Divisions I or II or from the Division III descendants of Benjamin Corssen (1686-1740). His genetic signature has a few close matches with individuals of English ancestry; we're beginning to consider that his ancestors may have come from the British Isles.


DIVISION II (Sussex Co., NJ) - 3 participants and 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 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 - 3 participants and results - Two Corson participants and one Courson participant remain unconnected to other participants in the project.


At least $400 remains in the subsidy fund to reimburse all or a portion of the test costs for six participants from particular family lines in Divisions I, III, IV, and X. You can see additional details at the project website:
