This is another collateral line of mine -- the second husband of a stepmother several times removed!
In March 1875 in Franklin co. TN, McCager Woodard (or Woodward) married Mary Jane, the widow of Jacob Holt. Mary Jane, whose LNAB is given as Deerin and Murphy depending on the document, had one son by him (James) but McCager was out of the picture by 1879 when she remarried to my 4x-great-grandpa, Benjamin Isaac Higginbotham.
I'm reasonably sure McCager is the same as "Mcigan Woodard" who's living in Bedford co. TN for the 1870 census with his wife Julia and three small children. I'm also fairly sure he's the same McCager Woodward who married Julia Astill in Jackson co. AL in 1863.
Then I found a record in Union co. KY, in which McCager Woodard gives permission for the marriage of his son Stephen. This is dated 1832, so I doubt this is the same McCager who married Mary Jane Deerin, but perhaps his father?
