The Bentley Family Project seeks to find common heritage through sharing of information and dna testing. The original Bentley Family Project separated YDNA through subgrouping of Families through assignment of letters and numbers. As new Administrators we will attempt to continue this to some extent. We are still researching the thought behind that process. Please email us if you can offer help on that. We might rename the subgroups and reshape. We will attempt to make daughter lines.
