Chris,Can you fill in some gaps as I'm not sure I'm following all of the sources correctly.First, my gg grandmother was Mary Elizabeth Alexander b. abt 1845 in Pickaway Co. OH (married James Addison Dresbach).She was d/o John Alexander b. PA and Margaret Martz (b. Northumberland, PA)John Alexander was a teacher, then sheriff in Pickaway Co OH.His father was James S. Alexander, b. 1798 Northumberland PA (m. Susannah Creitz d/o John Adam Creitz & susannah Streby).Information posted by others that I have not verified through source information says that James S. Alexander's parents were John Alexander b. abt 1760 and Nancy Stone or Stoner. James had siblings William, Robert, Sarah, john, Elizabeth, Rebacher, and Nancy.
Are you saying that the source of the information about Archibald Alexander being the father of Joseph and Samuel is the Highland Clan book you cite? or is there another source?Is there information in that Highland Clan book concerning any other Alexander family members who came to the Northumberland area with Archibald?Has DNA tied any of these together?Thanks for any information you can provide.
