My mother corresponded with Kay Groom Gibb a number of years ago. Unfortunately, we cannot find any of the letters they wrote to each other. I am not a direct descendant of Jonathon Alder but his brother Marcus who was born in 1776. Their father was Bartholomew and mother was Hannah Worthington. Do you have anything further back from Jonathon. I have Bartholomew's birthdate as 10 Feb 1734 - no location - and death as 1781 Wythe Co, VA. He had a wife Elizabeth which union produced a son John?. Then he married Hannah 16 Dec 1766 - Gloucester, NJ. I show them as having 5 more children with a sixth by a second husband after 1782 when she remarried. I would love to have more information about their ancestors.
