I'm looking for any documents that will prove the line from Abigail to Henry and from Henry to Caleb for DAR. My line is John, Henry, Caleb, Henry, Abigail, Ashman, Fred, Marian, Doris and although I have documents for everyone up to Abigail, I cannot find anything beyond Abigail. Any help anyone can offer would be greatly appreciated. Thank you.
