Individual Details

Family Tree has her name as Sarah Jane Plant - yet the Arkansas Marriage Index has this:
Thomas M. Brown, age 18 of Conway, AR, to Sarah Jane CASEY, 19, of Conway. Married 17 Jul 1862, Conway.

I did find her marriage to Charles M. Casey, 17 Jan 1861 in Conway Co. He was 22, she gave her age as 19. They were married by James H. Nicholas, JP

Strangely the tree also has her parents as John Plant and Elizabeth Middleton, but has attached the following 1850 Census which is not Sarah's family:
