I think I have a connection. You list the parents of Eleanor Jane Derby as Nathaniel Rhoads and Anna Brown. Could your Nathaniel Rhoads be the same as Doctor Nathan Rhodes Junior, born in 1764 in Dutchess County, NY, married in 1805 to Anna Brown, died 8 Dec 1861 in Dresden, Washington County, NY? If these are the same man, and my info is correct, I have a previous spouse "Mary" listed for Dr. Nathan Rhodes Junior; Nathan and Mary had 6 kids: David, William, Nathan III, Mary, Rowena and Daniel; I am descended from David and am searching for more info on his wife Parmeliann Derby (born 9 Dec 1796), nicknamed Milly. (I have Nathaniel and 2nd wife Anna Brown listed as having 5 kids: Eleanor Jane, Francis B, Rachel, Franklin, and Anna Brown Rhodes).
I think we must have been in contact before--your name sounds familiar to me.
