I have an Ebenizer b. 2/10/1650, parents were Ralph Allen & Esther Swift. He was one of their 11 children, Only the last two were girls. Ralph is George's oldest son, making George, Ebenizer's Grandfather.
Ralph never came to America but some of his children did.
Please let me know if any of our Allen info matches. The "other" George would have been 80 when he died if the 5/2/1648 date is his.
