1880 Lamar Co. TX census shows: Hartwell MARTIN (I believe this should be MORTON), his wife Rodey (b. c1844 MS), their childrenand Hartwell's mother-in-law, Nancy ALLEN, age 65 and born AR. Nancy is widowed. I am presuming that this Nancy is the widow of Zachariah.Perhaps this will help someone.
I am searching for the (Mary) Eliza ALLEN who married Middleton C. MARTIN 8 August 1855 in Itawamba Co. MS. I find this family in 1860 in Itawamba Co. MS, in Itawamba Co. MS in 1870 and in Marion Co.AL in 1880.By 1900 Middleton has remarried.
