Genealogical Sketches of the Allen Family of Medfield
The following tables are termed Sketches," as they do not pretend to give a complete genealogy of the family of which James Allen was the progenitor. Thus, of the nine children of James, I have taken only one, Joseph, the youngest son of james. And of the ten sons and two daughters of Joseph, I have attempted to trace the line of descent only through five of his sons. And, though I have sought information through such sources as were accessible, I have not been able to obtain complete and satisfactory answers relating to those five." -- Taken from the Introduction by Joseph Allen.
