Yeah, something doesn't quite add up with some of those dates. May not be the same people.
The Thomas Martin I'm looking for apparently has a death date of 30 Sep 1841 (at 68 years old) and Nancy Carr's is 14 Oct 1855 (at 71 years and 26 days old) both buried at Crandall, Harrison County, Indiana, USA.
Also, their daughter, Mary Martin Thomas is said to have been born 1807 in North Carolina, not 1827.
So I don't know what to say!
Another conflicting piece of info is that on General Joseph Martin's Wikipedia page, it says (speaking of his children):
"Another Martin son, and veteran of the War of 1812, was Thomas Martin. He also moved to Middle Tennessee where he married Georgia Carr (daughter of Dabney Carr). Alexander Martin, another son and veteran of the War of 1812, also moved to Middle Tennessee. He married Elizabeth Carr (daughter of John Fyndall Carr, also a Tennessean from Virginia), and after some years, moved to Missouri. "
It doesn't even say anything about a Nancy Carr, daughter of John Fyndall/Fendall Carr. So confusing!
It also says this on his Wiki page:
"The Native Indian connection of two members of the Martin family has created some confusion for some Martin genealogy researchers; Gen. Joseph Martin's brother, Capt. John "Jack" Calvin Martin, Sr., of his N.C. Rock House Plantation, a.k.a. Rock Castle Plantation, is often confused with his brother Gen. Joseph Martin."
