My Great-Great Grandmother EASTER, Esther, Ester D. MARK was born in Tennessee in 1817/19. She married my Great-Great Grandfather, William Garrison, b. 1810TN. William died in Denton County Texas sometime after the 1870 census and before 1880. EASTER died in 1899. Recently other family researchers have discovered that EASTER was of Native American ancestory, probably Cherokee, but could have been Cheyenne or Blackfoot. Any help with this Mark line would be greatly appreciated.
