I don't have your particular Leonard listed in my files, but I certainly would think he is a descendant of Leonhart Freshcoln. I note I have a Belinda McCord who married Elhannon Dampman (1815-1851). Belinda was a daughter of Benjamin McCord, who's sister Margaret married George Freshcoln, son of Leonhart.

This all look familiar and I would like to somehow determine the connection. Have you found him in the 1850 census yet?
