I am researching Cogans in western Pennsylvania and encourage anyone working along the same line to contact me. This lineage came to western PA prior to 1810 and primarily encompasses three groups. One is James who married Margaret Snyder Beckwith in 1809. Another is Jacob Ferdinand who married Maria Weaverling in 1829. The third is Jesse Cogan b. 1779 (location unknown) and married Anne (last name unknown) and lived in the Youngstown area. I am descended from this third group, but suspect that all three are related though I have no evidence. There was also a William Cogan living in Pitts Town (now Pittsburgh) around 1750 and he maybe the tie that connects these three families. Please feel free to e-mail and discuss. I have several thousand hours of accumulated data.
