I don't see a direct connection as your Orman & Hannah were married in Baltimore in 7/8/1821. At that time my Duvall line was still living in Anne Arundel Co., MD. Some of them did later move to Baltimore in the late 1800's. The Sarah E. Wheeler I have is living with Andrew Duvall b. 1818 and his father Eli H. Duvall born abt 1785. No relationship is listed on the census and I presume she must have had a relationship to Eli H. as they are about the same age. I was thinking she may be his widowed sister, but so far haven't found out anything to back up that theory. Let me know if you find out anything and I will do the same.
