__________________________
Introduction
Persons descended from David Cowan, the immigrant ancestor of the Pequea Creek Cowans, share a common YDNA signature. See: YDNA:Pequea Creek Cowan Signature. Other Cowans may also bear this or a similar signature if they descend from a relatively recent common ancestor with David Cowan's descendants. Currently, about 20 persons in the Cowan YDNA Project share this signature. (See: YDNA Signatures for background on YDNA Signatures.
Discussion
The following is based on the data recorded below.
Currently [1]there are 133 individuals in the Cowan Results at FTDNA. Of these, 20 (15%) have a YDNA pattern that corresponds within 10% to the Pequea Creek Cowan YDNA Signature. Six of the results identify ancestors that can be easily associated with immigrant ancestors to Pequea Creek. The other 14 results either provide no ancestral data to compare, or indicate an association with someone other than a Pequea Creek Cowan.
Geography | N | Earliest Ancestor

In most caes, we can probably assume that all of them share a common ancestor in the relatively recent past.
