I am looking for any assistance with locating records on Louis Lyon. He was my great-great grandfather and I have not been able to find any concrete information on him. What I do know is that he was born around 1873 and lived in or around Ohio. He was possibly married twice. His wife Margaret (Mary) was my great-great grandmother and she re-married and became a Norton and settled in Cortland, NY. My great-grandfather, Otis C Lyon Sr is his son. I have found records suggesting that he immigrated from Russia, but I have not been able to find his name on any boat passenger lists. Any help would be greatly appreciated.
