A belated thought about possible descent of your Moses Cavitt, b 1838,
Mississippi: perhaps he was the son of Alexander Tinnin Cavitt, b 1813,
eldest son of Moses(1786-1853) and Elizabeth B. Tinnin(1793-1839) Cavitt.
Married in Sumner County, TN, in 1812, Moses and Elizabeth moved to
Holmes County, MS, shortly after their first child, Alexander T., was
born,
Three more children were born to them before they moved around 1830 to
Yalobusha County, MS. Elizabeth died there in 1839 and in 1840, Moses
remarried. Two years later, Moses and his new wife sold their Yalobusha
County land to his youngest son and moved to Red River County, Texas,
where they produced seven children.
The only known facts about Alexander Tinnin Cavitt are that he was born
in Sumner County, TN, 20 August, 1813, grew up in Mississippi. Although
I have no other information about him and he was not mentioned (as were
two of his siblings) in his grandmother Tinnin's Will of 1836, that
doesn't necessarily mean he died young. Alexander was 25 years older
than your Moses.
I suggest you check for a head of household of the right age named
Alexander T. Cavitt in the 1840 Federal Census for Yalobusha County, MS.,
with a male in the household under ten. If not there, see if there's a
young female Cavitt head of household who has a male under ten. If still
no luck, check the entire statewide census index for Cavitts with a young
son. The odds are pretty long, but it's worth a shot.
Incidentally, while the surname Moses makes an obvious connection,
the surnames of subsequent generations which you listed do not echo many
of the surnames in the Cavitt branch of which Alexander T. is a part.
I hope these belated thoughts help.
