Many thanks for your reply. My descent from Isaac Allen-Hannah Douglas is:
Elizabeth Allen (16 Sep 1807 – 11 Nov 1879) m. Jonathan Field 17 Jan 1832 in Falmouth
Matilda Ann Field (14 Mar 1833 – 22 Jun 1922) m. Benaiah Niles 4 Mar 1853 in Brunswick
Eldora Maria Niles (22 Apr 1857 – 18 Sep 1952) m. Edwin Folsom Scruton 27 Aug 1884 in Lewiston
Arthur Edwin Scruton (20 Sep 1892 - ____) m. Theresa Costello 9 Apr 1916 in Boston. These are my grandparents.
I also have a copy of “Descendants of Walter Allen” and Vicki Lowe at the Freeport Library gave me the info from the Freeport VRs.
I have been trying to solve the following problems with Hannah:
1. Hannah was alleged to have been born in Durham, ca Mar 1780, but a search of the Douglas family records in The History of Durham does not show a Hannah of this period.
2. There is some confusion in the Freeport VRs: Isaac Allen Sen. children by his wife Elizabeth includes John Aug 12 1805, four years after Isaac’s marriage to Hannah ?
Isaac Allen Sen. children by his wife Elizabeth includes Charles Oct 3 1801, born after the marriage intentions date you provide of “9/19/1801” ?
3. The death records of two of her children, Amos and Hannah born in Freeport on 18 Nov 1818 and 12 Sep 1815 respectively, list their mother as Hannah Clark. The 1897 death record of Isaac's son Amos identifies Isaac as a sea captain. Maine Index to Vital Records 1892-1907. "Amos C. Allen, aet 79y 21d; married; carpenter; born Freeport, Me: son of Isac Allen sea captain, born Harpswell; and Hannah Clark, born Harpswell"
I have not yet found a birth record for a Hannah Clark in Harpswell. Perhaps Hannah was first married to someone named Douglas ? As the mother of Isaac’s first wife, Elizabeth Alexander, was Rosannah Clark, could Hannah have been a cousin of Elizabeth ?
