Thanks for your interest and effort, Bob. I did finally find our Ellen with a brother Samuel and sister Mary in the Philbrick and Philbrook Families Genealogy by Rev. Jacob Chapman of Exeter NH 1886. It seems to be a good compilation of the descendants of Thomas Philbrick 1583-1667. They were the offspring of Samuel b.15 Mar 1777, who was a son of Michael, b. 10 Nov 1734. Again, thank you.
