Hi Doug, You can email me directly at rourkkaren at gmail com I have much info on the Roark line. I have this line back to 204 and still going. My line originated in the Goose Creek, St Johns Berkeley, Charleston, & Catfish, Marion Co, SC area. I'm looking for DNA links to this line. I have some real problems on my line. I have a SAMUEL b. abt 1751, SAMUEL #2 b. 1767/1770 - 1850, SAMUEL #3 b. 1784. They may not be direct line. They also could be cousins. I believe I may be linked to your line even though our name is spelled differently. My line could not read or write and misspellings were common. They Samuels I believe were born 1751 & 1767 may be the same one.
