Searching for "Doc" Matthews, father of James William Matthews (b.1875) who was living with his mother Louisa J. and stepfather Ely J. Cleveland in 1880 Grimes Co. census. Doc was supposedly killed in or around 1874. James William Matthews married Mary Ann Duke. They moved from Texas with family to Oklahoma around 1899. Any info on Doc's given name or his or Louisa's ancestors would be appreciated.
