I don't know if I can be of any help or not. My mother was a Teasley. There are a lot of Teasleys around Troy Missouri. I have one aunt, Bernice Teasley Tillotson who has done a lot of family history and she might be able to help you. She has traced it back a long way. Her address is 702 Jack's Road, Troy, Missouri 63379. Her phone number is 573-898-2120. Her father's name was Benjamin Nelson Teasley. There were 12 children in my mother's family and all are dead but 3 girls. Bernice is the youngest and she is about 81 I believe but sharp as a tack. Our relatives came to Missouri from Ky or Tn. I think. You could write to her and I am sure she would be able to fill you in and see if there is a connection. There were several John Teasleys in our history I know. If I can be of any other Help contact me. Good luck.
