I have reached a dead end in researching my 2nd great grandfather. I can find no trace of him before he appeared in Lyon, KY. I have information that he was born in Lyon, KY on April, 1834 but I have no proof of that. I do have census information and know that he and his family were in Princeton, Kentucky from the time he married his wife in 8 Jan 1857 onwards. I have census proof that he and the family were in Princeton, Caldwell, Kentucky from 1860, 1870 and 1880. Matthew Lyon (or Matt L as he is referred to in some of the documents) died in 10 Nov 1887. I simply can not find a trace of his family, his parents - although I have had folks that wrote me and suggested that the family came over from Wales at the invitation of Matthew Lyon in Eddyville, Lyon, Kentucky. I have no proof of that. I can't go any further in my research if I can't find a link into Matthew Lyon Edwards' past. Can you help me?
I have a family tree also at ancestry.com - https://www.ancestry.com/family-tree/person/tree/25788559/person/12446901748/facts
