Hello, Mr. Allardice:
About 15 years ago, one of this message board's authors (can't remember which one, it might have been you) e-mailed me with that exact question. (On the old board, where one's e-mail address was displayed.) I told them I had found several members of his family in a cemetery in Colbert County, AL, & figured that Thomas J. was buried there with no tombstone/marker, but really didn't know. That was in either 2000 or 2001. I now live in South Texas, and cannot remember that cemetery's name. Let me look around a bit and holler at you. A man of his stature should have a maker, if not a historical marker.
I found a very interesting quote from Thomas J. Foster a day or two ago; I will post here later today.
Regards,
Hoyt
