Good Luck,These George Abbott's are a confusing bunch.In my Abbott publication "Descendants of George Abbott of Rowley, Mass., and Other Abbott Families" the intorduction of the book never states where George Abbott of Rowley Mass was born.It goes into varying possibilities in the introduction but it carefully alludes stating one as fact. The closest it comes to making a statement of fact is on page xvi of the introduction. It states the following: "It is pertinent to state here that all the names in this family are repeated in the family of George Abbott, Jr., of Andover, son of George Abbott of Rowley, Mass.; and it is among the descendants of the Andover George's son, John, that there is a firmly established tradition-which they will not acknowledge as such, but as fact- that his gr.-father, George Abbott of rowley, was the son of Sir Morris Abbott."
But the book is clear to state that this is still unproven and goes on to explain why Sir Morris Abbott of Guilford may or may not be George Abbott of Rowley's father.
If you ever do figure this out let me know.I would LOVE to know.I am just not certain how to prove something so long ago.I know this was probably not alot of help to you. Sorry. Pamela
