My search is for the origins of Rebecca E. McKinney b. June 1846 in Texas. She is known to be "part" Native American by family members who knew her. She married Thomas J. Donaldson and died in Milam Co Tx in 1915. Her father Uriah Newton McKinney married Elizabeth Norton in 1843 in Fannin Co Tx, he later had two more marriages. My question ---Who was the "Indian"? Uriah was born Tenn,have never made connection with any family,although many McKinneys settled in Milam Co Tx.from Tenn/Ala. Uriah served in the Mexican War and Civil War, is described as large man dark hair etc. No connection for Nortons. Was Elizabeth or Uriah from Indian Territory and married across Tx/Ok stateline,just across the river? Family stories tell of Rebecca's mother going back to her tribe,he got the children; Rebecca's mother was ill and he took the children and various versions of these.Rebecca told her grandsons that she did not live in a house as a young child. One elderly lady(grandchild of Rebecca) said that her grandfather met her grandmother at a springs; he hauled freight and would pass this place where he met Rebecca and her sister Minerva McKinney. I know that there were two reservations on Brazos River in or near Milam Co.although have yet to see any records. Uriah McKinney and Elizabeth Norton had Minerva (J.M.) 1844 and Rebecca E 1846 and possible Amanda 1850. Uriah and Melissa Unknown had Leynoa/Texoma 1853,Augustus 1856,Chesley 1858,Sarah 1860.He later married Elizabeth Lester ,widow,later in life. Children or Rebecca and Tom Donaldson were T.E. 1852(female,d. young?),W.U.male 1855(d.young?),Claude 1858,John Flemning 1882 Cleburn Chesley 1884. I know this is a long shot but included names etc in the event that it may matter to someone. I know no tribe name,no definite place of origin,no other family names.prior to this period of time. Wishing me luck, Marion Donaldson
