I have hit a wall in my family tree, my Great grandfather Elias Porter Gumbert was born in Allegheny Pennsylvania on July 25, 1861. I did find his parents names as George Gumbert and Mary Ann Sehn. This is where I can't find anything about his parents. He listed his parents as born in Penna on his marriage certificate. On the 1880 census he was listed as a stepchild of Samuel Heasley. Any help would be greatly appreciated. Thank you, Aaron
