A Genealogy of the Allen Family, 1568 - 1882
This book does not contain a complete genealogy of the descendants of George Allen; but only of those families to whos registers access could be obtained. With all the imperfections, it is thought best to embalm these fragments in print before the records are irretrievably lost. ... A genealogy of this branch of the Allen family was compiled by William Allen, late of Norridgewock. This work has been the basis of this genealogy. -- Taken from the Introduction by Joshua Allen.
