I am searching for links to a Samuel Cooper, married to Susan Harris.They had a daughter Mathilde, born in Erie, Pa. in 1843. Mathilde married Luke Lister approx 1860, and I believe they lived in Belmont Co.Both Luke and his daughter Lucy appear on the 1880 census, living in Washington Twp, Belmont Co. It was approx 1881-2 that Lucy married Brian Halpin. I need help with the Coopers, Listers, and Halpins. Does anyone have information on them? Thanks for your help.
