Corson Surname DNA Project

Since last issue's report, three participants joined the project and six participants received results. Results for one participant allowed us to establish the ancestral genetic signature for another Corson family Division.

Division I

It has been a busy period for Division I; descendants of three of the four sons of Samuel Corson (c.1686-1764) received results. A Colson participant (#25) who believed that he descended from Samuel's third son Samuel Colson (1719-1810) (Div. I-D) had a genetic signature that 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. A Corson participant (#28) who traced his descent from youngest son Ichabod (c.1725-1801) (Div. I-F) had a genetic signature that matched Samuel's on 42 of 43 markers, which corroborated his documented male-line ancestry. Participant #28's genetic signature differs at marker DYS 458, which may indicate a marker value we can use to identify descendants of Ichabod. Another Corson participant (#29) traced his descent from eldest son Zebulon (1712-1786) (Div. I-A) and had a genetic signature that matched Samuel's on 42 of 43 markers, corroborating his documented male-line ancestry.

With the participation of Participant #28, the project has tested at least one descendant of each of Samuel Corson's four sons. With the participation of Participant #29, the project has tested at one descendant of each of Zebulon Corson's four sons.  You can see how Division I participants are related in their common documented descendancy chart on the project website: http://www.geocities.com/misccorson/dna/DivisionI.gif

Division Va

The Corson participant (#23) who documented 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 IV: Progenitor Genetic Signature Established

A Corson participant (#26) who documented 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), of Maurice River Township, Cumberland Co., NJ, indeed descended from Division IV.
