Can you go back one generation with your Devlin line? My ggrandfather, Patrick, came to Philadelphia about 1852. He had family members who went to England somewhere near Newcastle perhaps). Family names that might duplicate are: Patrick and Lawrence (brothers), William, Thomas, Mary Teresa, Margaret, Frank, Anny, and Lawrence. William had a son Charles. This is only a shot in the dark. Ours may have lived in Ballyclare, Co Antrim. Hope we can connect.
