I am seeking information about the family of my great-grandmother Martha Jane Brewer. She married my great-grandfather Samuel Nelson Mabe in 1855 at Rogersville, Tennessee. They were in the Sullivan County census in 1860, the Laurel County, Kentucky census in 1870, and the Hancock County, Tennessee census in 1880. She was born on October 02, 1837 in Tennessee and died in Caliborne County, Tennessee on November 07, 1902. There might some confusion on her maiden name. In my great-grandfather's pension application she is listed as a Seals, but on her son's James' death certificate she listed as a Brewer. I cannot find any information about her family Seals or Brewer in the 1850 census records. Any help would be most appreciated.
