I was google-ing Elisha Allen to see if I could find any more information on him and came across your posting at Genealogy.com here is what I have on him at present:
Elisha Allen was located on Harpswell Neck, Maine, Lot Number 4, Prior to 1740. The Descendants do not remember the town from which he removed to Harpswell, Maine, they believe that his home town was York, Maine. The name of his father is not recalled. The mother's maiden name was Dorothy Hoddyhorn. Elisha Allen was an industrious farmer and a man of sterling qualities. 2. Elisha Allen was the son of James Allen and Dorothy Barsham of York, Maine. Elisha was born June 18, 1709. Ref.: York Vital Records, (see N.E.G.H.R., 1956, page 93). See also York Deeds, Book 30, Page 197; Book 31, pages 141 and 142. Book 31, page 194 also states Elizabeth, wife of Elisha Allen, was the daughter of Andrew Toothaker.
