I have traced my husbands ancestor,Thomas Briggs born abt 1770 and Lucy Holt to Kentucky in the early 1800's. Thomas was born in PA. I have confirmed that they had at least two sons, 1) James B Briggs born June 7,1799 KY and 2)Andrew Briggs born about 1803 in Kentucky. Other poss children: Mary, John, William and Elizabeth. Thomas and Lucy's names and Thomas's birthdate match up with your Thomas and Lucy Holt Briggs. Would you know if they are in fact the same, Thomas and Lucy as yours.
