I believe Patsy Flower(s) was the first wife of Cornelius Vermillion b. 1780 VA, son of Francis Burch Vermillion and Nancy Griffith. Cornelius had a younger brother Nicodemus Vermillion b. 1794 VA d. 1828, who married twice: first to Sally Howard, second to Martha Willcox. I don't know Nicodemus' children, but Cornelius' sons don't include any named Nicodemus.
Cornelius and his brother Nicodemus also had an uncle named Nicodemus Vermillion (b. 1676 MD, d. 1863)-- he was brother of their dad Francis Burch Vermillion. Sorry I don't have his family info.However it's possible he named a son after himself -- the Vermillions tended to use favorite names over and over!
And to add to the confusion, Francis Burch and Nicodemus Vermillion had a brother Uriah Vermillion -- who (of course:) named one of his sons Nicodemus (b. WV after 1803).
It's ironic that we have a Patsy Flowers marrying Cornelius and not Nicodemus, given your info. I'm not sure what to make of that.
