Larry, there might be some descendants but I couldn't say for sure as I don't any personally. I don't know of anybody with the surname of Dunlavy either. But if my memory sures me correct Margaret had a sister who did live in the county of Cullman also...My husband was from the county of Cullman, lived on Shelton Grove Mtn. His grt. grandmother was Margaret Malinda Dunlavy, dau. of Braxton Dunlavy & Elizabeth. LDS says Braxton died in Cullman but I haven't found anything to prove that but I know his wife did.
