Hello cousin.
The Abraham Tegarden book includes your grandfather's name with birth date August 28, 1930.
We descend from Aaron Teegarden (April 08, 1786 - May 1879).
He is the 9th child of George Teegarden (1744 Pennsylvania). Aaron settled in Ray County, Missouri in the 1830's after a short stop in Knox County, Ohio. His younger brother Jobe joined him in Ray County about 10 years later.
Please contact me and I will fill in the family tree for you.
