I'm sorry, but have no record of a Jane as a daughter of Samuel Snead/Sneed.His children may have been too soon for what you are looking for.The known names are: Emilyb.abt 1755 Stephenb. 2/1756 Hannahb. abt. 1760 Philipb. abt 1762 Johnb: abt 1764 Nancyb: 10/1766 Dudleyb: abt 1768 Thomasb: 7/1772 Lemuelb: abt.1774
It's possible one of them had a daughter by that name, but so far none with last name of Snead/Sneed.There was Nancy's daughter, Jane Dudley Gooch, who married Wm. Clement; and Hannah's daughter, Jane Wiilams, who married G.Hardin and J.Black. The Snead/Sneed family was a large family in Granville originally, so any one of them may have had an offspring by that name, but I haven't found any in the Marriage Indexes yet.
