John Brinkley married Docia Ann Gilliam or Tidwell,in Independence Co AR about 1860 give or take. their son, John Richard Price Brinkley was born 1864.Would like to learn more about their families and which was Docia's maiden name. I have information on their descendants, if any one wantsto share.
I find John in Independecce Co in 1860 census and in Craighead Co in1870 but don't find him any more. think he died because I finr her as wife of Joel Miller in 1880 with J.R.P. and a daughter Margaret Jane.
