I think that Pressley's second wife, Martha E. Winters, was born Martha E. Booth(e) in SC ca 1830. Martha, her mother, was born in 1800 in SC. U.S. Censuses of 1860, 1870 and 1880 show the mother living with or near daughter Martha. In 1880 daughter is listed as M.E. Naisworthy, age 50, "keeping house" in Muscogee Co GA. Living with her were son M. E. (Martin) Winters, age 19 and mother M. Booth, 80, born in S.C.
Pressley Norsworthy had married Martha E. Winters, widow, in Dec 1874 in Butler Co. AL. Her age then was shown as 45. By the time of the 1880 Census, Pressley and family remain in Pike Co AL, but Martha has left for GA. She does give "Naisworthy" as her last name.
So far I have not fleshed out this sketchy information.
