I have also had my DNA tested by the Family Tree DNA testing company. There was/is a match between my DNA test results and Roman Paul Barnhart, Jr.'s DNA test results.

Following the paper trail back in time for Roman Paul Barnhart leads to Roman's great, great grandparents, a couple I refer to as old David and old Margaret Keefe/O'Keefe. Following the paper trail back in time for me leads to my great, great grandfather, John Keefe/O'Keefe. I believe my DNA match to Roman indicates my great, great grandfather John Keefe/O'Keefe was a child of old David and old Margaret Keefe/O'Keefe.
