Your Nicodemus Vermillion was likely the son of Reuben and Rebecca (Compston) Vermillion. I have a great deal of info on his ancestry and siblings, but nothing that post-dates his birth and his family's move to Missouri. His father, Reuben (b. 1800), was a son of my gggg-grandfather, Uriah Vermillion, and a half-brother of my ggg-grandfather, Jesse Vermillion. Reuben and Rebecca lived briefly in Indiana and Illinois during their migration from Lawrence County, OH to LaClede County, MO and then Barry County, MO.
If you'd like this info, e-mail me and I'll do my best to get it to you either via e-mail or USPS.
