Do you have their approximate birth dates or marriage date?
I have two Martha Actons in my file but no husbands.
Martha H. b 17 Sep 1848 , d. 1861 and buried at Old Acton Cemetery in Shelby Co. She is the daughter of John Acton, Jr and Martha Turner Booth. Since she is only 13 when she dies it is doubtful that she could be the one you need.
Martha Patsy, b 2 Oct 1812 d. Unknown. She is the daughter of John Acton, Sr and Jennie Roberts. She is the sister of John Jr. mentioned above.
I'm not closely connected to the Acton Family but will be glad to help any way that I can. I live in Shelby County.
