I am not researcing this family, but have a little information in the booklet "Northern Virginia Genealogy, Vol. 4, #4, Fall 1999:
"Marriage Bonds, 1784, Fauquier County, by Joan W. Peters - 029 7/26/1784 - Jacob Stadler to Elizabeth Horton, Bonsdmen:Jacob Stadler (Seal), Alex Bradford (Seal), Witness:G. Brooke.030 11/2/1784 - Robert Stadler to Mary Shanks, Bondsmen:Robt. Stadler (Seal), Jno Berryman (Seal), Witness:G.E.O. Brooke."
You have a great deal of information, but I thought you might be interested in this.
