Actually, I have some information on Kingsbury.Kingsbury is the son of Nathaniel and Susannah Sergent Donnell. And grandson of Benjamin and Sarah Donnell.He is the 8th child of 8 children.This if verified by the will of Nathaniel , Kingsbury's parents. Also by a manuscript of the Donnell Family compiled by George Ernst.
I am the great great great granddaughter of Kingsbury's older brother, Samuel Donnell.Benjamin Donnell (8 Mar 1787 - 28 Sep 1869)m. Rebecca Davis, had a son named Kingsbury (9 Feb 1822 d.?) also.This is verified through Lisbon Falls, ME Town Records and Donnell Family MS.
My Aunt Shirley Donnell research the family name extensively in Maine and mostly provided details of our direct decendents.Other family members are mentioned, but there is very little detail.I would like to add details if they are available.
