Corson Surname DNA Project Newsletter – April 2006

Hello everyone,

In the past month, two participants received their test results, and one participant signed up.  This has been another red-letter month for the project, with the two most recent results allowing us to (1) estimate the ancestral genetic signature for another Division and (2) confirm the ancestry of two participants to two Divisions.



27 participants, 26 test results reported

Separate family lines: 13 (1 set of five participants, 1 set of four, 2 sets of three, 2 sets of two, 7 unmatched)

Family-line haplogroups: 9 in R1b; 1 each in E3b, I1a, I1c, and J2

Average time for lab to process a DNA sample: 13 days

Average time from sign-up to receipt of test results: 34 days


DIVISION I (New England) – 5 participants and results

The 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), received his results.  His genetic signature matched the Division I ancestral genetic signature on all 43 markers tested, confirming that he almost certainly descended from Cornelius Cursonwhit.  Thus, we now know that we’re looking in the right direction for documentation to connect the participant’s earliest known Colson ancestor, John B. Colson (c.1802-aft.1870), to Samuel Colson.

DIVISION II (Sussex Co., NJ) – 4 participants, 3 results

A Corson participant (#27) who documents descent from Benjamin Corson (1827-1901) recently joined.  Many researchers consider that Benjamin’s father was Abraham Corson (c.1779-1851), a Division II descendant, but some believe that Benjamin may have descended from a Division III (Staten Island, NY) Corson.  Consequently, the results of this test may confirm whether Benjamin Corson descended from Division II or Division III. (participant number later re-assigned)

DIVISION IV (Cape May Co., NJ) – 4 participants and results

The Corson participant (#26) who documents descent from John Corson (c.1660-1728) via his great-grandson Joel Corson (d. 1823) received his results.  His genetic signature matched that of two other documented descendants of progenitor Carsten Jansen (1634-c.1697) on 41-42 of 43 markers tested, allowing us to estimate the ancestral genetic signature of Carsten Jansen himself.  Now that we know the ancestral genetic signature of Division IV Corsons, we can search for genetic matches in Europe that might indicate Carsten’s region of origin.  We also have been able to confirm that the earliest known male-line ancestor of Participant #6, William Corson, Sr. (bef. 1775-aft. 1823), indeed descended from Division IV.

DIVISION Va (Dumfriesshire, Scotland) – 1 participant and result

The Corson participant (#23) who documents descent from William Corson (c.1735-1802), of Scotland, received his results.  His genetic signature doesn’t match that of any other participant in the project, indicating that Scottish Corsons may not be genealogically related to any of the other known Corson families.  We’re looking for another Scottish Corson descendant so we can estimate the ancestral genetic signature for this family.


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 VII (Hunterdon Co., NJ) – 2 participants and results – Now that have 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 $365 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, and X. You can see additional details at the project website:
