Brenda, If your Mary Ann was born in Maryland or Virginia while "at sea," it is very unlikely she is the daughter of Uriah (b. 1761).Uriah was my gggg-grandfather and our family has passed down a very complete history of his two marriages.Uriah and first wife, Susannah Barker, had a daughter named Mary Susan born Sept. 9, 1791 in Prince George's County, MD and she died June 25, 1875 in Lawrence County, OH having married only once in 1809 to Jacob Powell. This couple had 14 children, died in the same year of 1875 and are both buried side-by-side in Myrtle Tree Cemetery in Arabia, OH. Uriah and his second wife, Elizabeth had only two daughters named Lucy and Harriet. There was a Uriah Vermillion born 1753 in Maryland who had at least one child, a son named Levi (often called Lewis) Vermillion (b. March 6, 1784 in Fauquier County, VA. I have never found this Uriah's wife's name or the existence of any other children.I do have several letters, though unverified, that state Levi served briefly in the War of 1812.I also have received information from others, again unverified, that Levi later moved to Missouri, but I know not where in Missouri he settled.My bet is that if your Mary Ann had a father named Uriah, it was more likely this Uriah born in 1753.And I have found this Uriah to be very hard to research.I can tell you with a great degree of certainty that the family history handed down to me shows that Uriah born 1761 had no daughter named Mary Ann and that no one from his line ever married into the Follin family. I hope this is helpful in your quest, and best of luck!
