Hi Angela,
Yes, Thomas A. Coulter is the reason I started researching the Coulter's, he is my 3rd great grandfather. I do have a lot of information on him, his Civil War pension papers, an old picture of him with his wife Dicy Faulkenberry, as well as many other documents that my cousin Lana and I gathered on a research trip we took to Missouri. How do you think you're connected? If you give me some names and dates I can probably tell you if you're connected and would be happy to share what I've got on him.
I look forward to hearing from you!
Tami
