My condolences on the passing of William Mains. I stumbled upon your entry in Ancestry.com when looking for information on my ancestor William E Mains of Mckeesport (1841-1872?). The 1870 census shows he was married and had a daughter Naomi. Naomi was my great-grandmother and that would make William my great-great-grandfather. If you know any information about these two or wife/mother Celestia Anna Lynch, I would appreciate hearing from you.
