The only Rebecca I show in my line was b. 5 Oct 1724 in St. George's Parish, Balt. Cty, MD. She was the dau of Cornelius/Ann Emson Poulson.No further info on her. Your ties to Frederick Cty would indicate possible ties to my line.I am not familiar with any of your other given names tho and am unaware of any of my line moving to WV.
