Corson Surname DNA Project Newsletter – February 2006

Hello everyone,

Since last month’s report, one new participant signed up and one received his test results. 



22 participants, 21 test results reported

Separate family lines: 12 (4 sets of three participants, 1 set of two, 7 unmatched)

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

Average time for lab to process a DNA sample: 11 days

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


DIVISION I (New England) – 4 participants, 3 results

A new participant (#22) with the surname Corson signed up this month.  Like two of the participants from this Division, he descends from Zebulon Corson (1712-1786); however, he descends from a different son of Zebulon: Aaron (c.1741-c.1812).  If his results match those of other Division I descendants, the project will have tested descendants of three of Zebulon’s four sons.

In addition, a documented descendant of Zebulon’s brother Hatevil (1714-1798) (Div. I-B) recently expressed an interest in the project.  We hope that he will participate.  If so, we would be able to compare his genetic signature with that of participant #12, who also descends from Hatevil.  In the meantime, we are still looking for male-line descendants of Samuel Corson (1719-1810) (Div. I-D) and Ichabod Corson (c.1725-c.1800) (Div. I-F) who would be willing to participate.

DIVISION III (Staten Island, NY) – 6 participants and results

Participant #21, with the surname Vroom, received his results today.  His genetic signature matches that of the other two Vrooms in the project; thus, it corroborates his documented genealogy.  His genetic signature matches exactly that of Participant #17, his fourth cousin, once removed.  Consequently, it is almost certain that their most recent common ancestor, John Vroom (1757-1833), had the same genetic signature that they do.  The other Vroom participant, #13, matches them on 41 out of 43 markers, indicating a slightly more distant relationship.  Their genealogies corroborate this, since he is documented as their sixth cousin.  All document descent from Hendrick Vroom (1683-1769), grandson of Division III progenitor Cors Pieterszen (1612-1655).  However, among the six participants who believe that they descend from Cors Pieterszen, we have found three different genetic signatures.  Only one of these genetic signatures can represent Division III.

To figure out which one does, 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) represents that carried by Cors Pieterszen.


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 IV (Cape May Co., NJ) – 4 participants and results – We need to find just one more matching participant from this Division to resolve the uncertainty about progenitor Carsten Jansen’s (1634- ca. 1697) genetic signature.

DIVISION VII (Hunterdon Co., NJ) – 1 participant and result – The participant from this brick-walled Division has yet to match anyone closely.

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 V, 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.


I recently discovered that DNA Heritage, a testing lab that tests the same markers as Relative Genetics, is having a sale on its 43-marker test until 7 March.  So, I’ve set up a Corson DNA project there.  If you know of anyone who has been waiting for the price to come down, now would be a good time to join.  Until 7 March, the test price will be $137.77, $57 less than the usual test cost at Relative Genetics.  You can read more about the DNA Heritage and how to join the Corson DNA project there at


At least $495 remains in the subsidy fund to reimburse all or a portion of the test costs for eight participants from particular family lines in Divisions I, III, IV, VII, and X.  You can see additional details at the project website:
