Actually, there IS a connection between the James Allen family and the Ethan Allen line, but I admit the relationship is distant. Eva's ancestry for James Allen is correct, but it needs to go back one more step, as follows:
James and Mary Akin Allen, then to Ebenezer and Abigail Hill Allen, then to Ralph and Esther Susannah Hill Allen, then over to England to George and Catherine Starke Allen.
As for Ethan Allen, my information shows that this Englishman, George Allen, had eleven children one of whom was Samuel Allen. Ethan Allen's line goes back first to Joseph to Samuel-2 to Nehemiah to the Samuel-1 who was also the son of George. So they are related, but you have to go back to England to connect them.
