Thomas Peter Carnes Lott is my 3rd great grandfather. I unfortunately do not carry the Lott name, but my 99yo grandfather John Freeman Lott, is still alive and my uncle, Freeman Lott is living.
I am not sure of the Robert W Lott line. I have TPC Lott's full brother as being Robert Rufus Retilius Lott, both come to Texas in the early 1840's.
You can find TCP Lott's gravesite and many of his decendent in the Pettus Lott cemetery in Goliad Co Texas. It is updated on FindAGrave.com
If you are looking into TPC and his brother, do you by chance know of a possible third full brother, maybe a doctor or a pharmacist, who was killed over a woman in Mississippi?
And if you have any information on TPC's father (William Lott) first wife, that would be helpful too. I know that William married Kilrennia Jenkins in 1816, but this is 7 years after TPC was born, so there must be another wife.
