Died 1870.
There's a Thomas with these children in the 1850 census except for Lewis Rowland Lanier and wife is Elizabeth.
1850 census: https://www.ancestry.com/sharing/2854677?mark=7b22746f6b656e223a224...
There's a TB Lanier in 1860 census: https://www.ancestry.com/sharing/2854742?mark=7b22746f6b656e223a226...
It would seem Elizabeth is a second wife.
Then Mary widow Terry a third wife
There's a T. B. Lanier married Mary Terry 1867

But there's a will with wife called Esther
And the Geneanet and FAG folks have a Nancy Rowland Sadler but she died in Arkansas and had 11 children with William Sharp so these are not the same woman.
I disconnected Nancy Sadler and am awaiting her to be disconnected from him at Findagrave.
Different state.
Probably confused with Nancy Rowland Lanier but still looking and not likely to get them situated today-- just discovered them while working on Giddens
Will:
https://www.ancestry.com/sharing/2853556?mark=7b22746f6b656e223a226... is probably a different man and perhaps the same man as in the 1850 and 1860 census?
I will add a profile for the man with the will but think they may be related.
