Seeking Information on Lucas Simpson Born 1 1882 IN Kentucky

I am trying to find information on Lucas Simpson. Lucas was born 1/1882 in Kentucky. He was the son of Elijah Simpson and Celia Gentry. He married a Vera Unknown and had two children that i know of Mollie R. Simpson and Maud Simpson. I found him living in Hart County in 1910 but before and after that i have lost track of him. I am looking for a death dates possible marriage dates and a maiden name for Vera. Willing to share what i have on the Simpson and Gentry Family. Thanks Crystal
