I don't know if this is any help to you, but here goes...My Allen connection is through the Bibber and Coffin side of my family.My great Uncle Richard A. Bibber married a Sylvia W. Allen of Maine (Richard was born in Yarmouth, ME), and a great Aunt of mine Edwina Louise Coffin of Freeport, ME married a Daniel P. Allen.And that's it. I know it isn't much but that is all I have. Richard Bibber was born Apr.2, 1908 d. 1967, and Edwina was born May 26, 1876. I have no dates for you for the Allen's. Let me know if I can be of any more help to you. Good Luck.
