Seven Brother Cowans
Category:Seven Brothers YDNA
[edit]

Analysis

Source:Fleming, 1971 identifies a large froup of Cowans as descending from "Seven Brothers" whose earliest ancestors are said to have come to America from County Down, Ireland with the so-called "Wigton Walkers, both groups settling in Old Chester, PA. While there are connections between the Wigton Walkers and some lines of Cowans, there is no evidence to show that the Cowans

  • came from County Down, or that
  • they came to America with the Wigton Walkers, or that
  • they settled in Old Chester.

Nonetheless, there does appear to be a large, possibly inter-related group of Cowans, who settled in Old Augusta, the Carolina Cradle, and in Southwestern Virginia. YDNA evidence (below) shows that some of these Cowan's are in fact closely related. We do not know, in many instances how those relations run. Identifying those relations is a major problem in Cowan genealogy, for which YDNA studies may eventually yield a solution.

The data below is based on a "Seven Brothers Signature" originally developed based on YDNA data for a descendant of Robert Cowan and Susannah Woods. Robert is identified by Fleming as a member of the Seven Brothers family line. Other kits were examined in terms of how closely they matched that of the Robert Cowan descendant. From the results of those kits, a composite YDNA signature (currently designated the Seven Brothers Signature) was developed. All kits in the Cowan YDNA test were then compared to this composite signature.


[edit]

Data

Key:

Dark Blue coding, relatively recent common ancestor. (Step and marker indexes both less than or equal to 0.12)
Lightblue, marginal results, (Step index greater than 0.12, but Marker index still less than or equal to 0.12
White, no expectation of a relatively recent common ancestor (Both step and marker index greater than 0.12)

Lineage Coding:

Grey, *YDNA patterns inconsistent with tests for other individuals tracing to the same ancestor.
PaleGreen immigrated from (or descendant living in) Ireland post 1800
Thistle immigrated from (or descendant living in) Scotland post 1800
Orange immigrated from (or descendant living in) North Ireland post 1800
