Margaret Malvina’s husband was Robert King Thompson (the 2nd great grandfather of my brother-in-law). Here is information that I found on line about the farm that Robert owned. (In all of the US census records I could find, he listed his occupation as farmer.)
Robert King Thompson “Born August 23, 1818 – Died March 28, 1898” Burial: Bethel Church Cemetery, rural Lawrence County, Mississippi. Bethel Church was the family’s “home church” for several decades. The church is still standing in excellent condition and is the gathering place for the annual Thompson family reunion.
“Pursuant to the Act of Congress on the 20th day of May, 1862, To secure Homesteads to actual letters on the Public Domain,” and the acts supplemental thereto, the claim of Robert King Thompson has been established and duly consummated in conformity to law, for the West half of the South East quarter of Section two, in Township eight North of Range twenty West, the the District of Lands, subject to sale at Jackson, Mississippi containing one hundred and fifty Acres and Sixty hundredths of an acre.
