Corson Surname DNA Project Newsletter - 20 October 2005 

Hello everyone, 

Since last month's report, one new participant signed up. This report also contains an update about the subsidy fund.



18 participants, 17 test results reported 

Genetic matches: 2 sets of three, 3 sets of two, 5 unmatched 

Separate family lines: 10 (7 in haplogroup R1b; 1 each in I1a, I2*, and E3b) 

Average time for lab to process a DNA sample: 10.8 days 

Average time from sign-up to receipt of test results: 35.3 days


Division X (Unknown) - 3 participants

A descendant of James Courson (b. ca. 1762 in Lancaster Co., South Carolina) joined the project last week. James Courson served as a private in the Revolutionary War, and many of his descendants live in Alabama, Georgia, and Texas, among other places. The parents of James remain unknown. I'll be excited to see if his descendant's results match that of one of the families already tested in the project. If not, James may have descended from an as-yet unrepresented family, such as a French Courson or Scottish Corson line.


Division I (New England) - 3 participants, 3 results

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 II (Sussex Co., NJ) - 2 participants, 2 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) - 4 participants, 4 results

We are still looking for male-line descendants of Benjamin Corssen's (1686-1740) brothers Jacob (1681-1742) or Christian (1676-aft. 1764) and Hendrick Vroom's (1683-1769) brothers Cornelius (b. 1677) or Alfred to participate. Until then, we won't know if the Corson or Vroom genetic signature (if either) represents that carried by progenitor Cors Pietersz (1612-1655).

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

We need to find at least one more 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, 1 result

The participant from this brick-walled Division has yet to match anyone closely.

Division VIII (Colsons not derived from Corsons) - 1 participant, 1 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 XIII, V, VI, and IX - 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 Corsan / Courson / Curzon / Korson families.


The Corson/Colson Family History Association (CCFHA) recently allocated an additional $200 to reimburse a portion of the test cost for five participants from particular family lines in Divisions III, IV, VII, and X. You can see additional details at the project website:

We greatly appreciate the CCFHA's assistance. With this new allocation, the subsidy fund now contains pledges of $535. To date, the project has disbursed $1085 to help pay for 12 participants' tests.
