Corson Surname DNA Project Newsletter – 9 June 2005

Hello everyone, Since last month’s issue, we’ve welcomed 3 new participants and received 2 new test results. Here’s the summary and details:

Project Statistics:

15 participants, 13 test results reported

Genetic matches: 1 set of three, 2 sets of two, 6 unmatched

Genetic family lines: 9 (6 in haplogroup R1b; 1 each in I1a, I2*, and E3b)

Average time for lab to process a DNA sample: 10.6 days

Average time from sign-up to receipt of test results: 33.8 days

Updates by CCFHA Division:

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

Results for the descendant of Hatevil Colson (1714-1798) (Div. I-B) arrived on 15 May. They matched the results for the 2 descendants of Zebulon Corson (1712-1786) (Div. I-A) on 40 of 41 markers. This close match establishes the genetic signature for Samuel Corson (1686-ca. 1765), the son of this Division’s progenitor, Cornelius Cursonwhit. (Since Cornelius had no other known sons, we cannot deduce his genetic signature directly.) Assuming that Cornelius had the same genetic signature as his son, he belonged to haplogroup R1b, a broad genetic group that occurs throughout western Europe. Certain groups of markers in his genetic signature have values that appear to occur somewhat more frequently in Anglo-Saxon/Germanic regions of Europe than elsewhere, but the existing Y-DNA databases currently contain too few data to know for certain. As the number of people tested increases, we hope to find someone in Europe matching Samuel’s genetic signature. In the meantime, we are still looking for male-line descendants of Samuel Corson (1719-1810) (Div. I-D) who would be willing to participate.

Division II (Sussex Co., NJ) – 2 participants, 1 result

A participant with the surname Corsa who traces his ancestry to this Division’s progenitor, Jan Corszen (d. 1703), through his son Benjamin Fletcher Corsse (1692-1770) signed up last month. His documented male line begins as follows: Jan Corszen > Benjamin Fletcher Corsse > Isaac Corsa > Andrew > Isaac. We look forward to seeing his test results.

Division III (Staten Island, NY) – 3 participants, 3 results

A participant with the surname Vroom who traces his ancestry to this Division’s progenitor, Cors Pietersz (1612-1655), through his son Hendrick Corssen Vroom (ca. 1653-?) signed up and received his results last month. His documented male line begins as follows: Cors Pietersz > Hendrick Corssen Vroom > Hendrick Vroom > George > Hendrick D. His genetic signature does not match those of two descendants of Benjamin Corssen (1686-1740); thus, either he or they do not descend from Cors Pietersz. We are looking for another male-line Vroom descendant of Cors Pietersz willing to participate; comparing his results with those of the new Vroom participant may help us determine this Division's genetic signature. Also, we are still looking for male-line descendants of Benjamin Corssen's brothers Jacob Corssen (1681-1742) and Christian Corssen (1676-aft. 1764) who might wish to participate.

Division IV (Cape May Co., NJ) – 4 participants, 3 results

A participant who traces his ancestry to this Division’s progenitor, Caersten Jansen (1634- ca. 1697), through his son John Corson (ca. 1660-1728) joined last month. His documented male line begins as follows: Caersten Jansen > John Corson I > Jacob > Jacob II > Eli. Currently, two other participants have documented descent from Caersten Jansen, but they carry different genetic signatures. One of them matches a descendant of William Corson, Sr. (bef. 1775 - aft. 1823), who remains brick-walled. If the genetic signature of the new participant matches these two, we’ll have the ancestral genetic signature of Caersten Jansen and can remove William Corson, Sr.'s brick wall. If, however, it matches the other Division IV participant instead, we’ll have the ancestral genetic signature of Caersten’s son John Corson.

Division VII (Hunterdon Co., NJ) – 1 participant, 1 result

The participant from this brick-walled Division has yet to match anyone closely. He has contacted people who may be distant relatives, hoping to find one willing to participate.

Divisions XIII, V, VI, and IX – no participants

We're still working to recruit living male-line 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.

Unconnected – 2 participants

We're performing reverse genealogy to identify potential relatives of both of these participants.

Subsidy Fund:

The CCFHA still has $40 reimbursements of test costs available for the next 2 participants. We may be able to find additional funding for participants from particular family lines that would help us establish ancestral genetic signatures. Those unable to submit a DNA sample directly (e.g., not descended in the direct male line) can participate by helping to subsidize the test cost for someone else. For many people, the test cost ($195) is the greatest barrier to participation. Please contact Michael Corson if you would like to help subsidize a portion of a participant’s test cost.
