Follow up to my own research. Apparently, Martha Coker did marry Foster Rowen after she left Arkansas for Texas to visit her Aunt Henrietta Fancher Spaulding in Waxahatchie Texas. However, Rowen died and she returned to Carroll County, Arkansas and lived with her brothers. In 1871, she married Thomas Fancher Sisco Jr and had one daughter, Margaret, but Martha died sometime between 1873 and 1877 when TFS Jr remarried. Martha's name was always Martha Jane Coker and she was called "Mattie." She was never Martha Fancher Coker, but she did live for a short time with her grandparents, James and Elizabeth Fancher after her mother, Arminta, died after the birth of her little brother, George Dallas Coker.
