My father, Stephen D. Barnett was born in 1948. He was separated from his father, Arthur A. Barnett (b.1911-d.1989)at the age of 4.

Arthur's family lived in Yeso, Chaves, NM when the 1910 census
was conducted.
Stouder Lee Barnett (1862-1924) worked on windmills. His wife, Helen was born around 1874. Arthur's sister, Mary was born around 1908.
I would be greatful for any additional information.

If you are unaware of it,and it may hep: I think you can go to

United States records
Oklahoma County Marriages 1891-1959
and find the marriage certificate of:
S.Lee Barnett age 39 and Hellen Smith age 30;handwriting a bit difficult-gives his parents as something like D.G.Barnett and Elizabeth Woolridge. Witnesses were Arthur Smith, and Anna R.Smith--the marriage took place at the home of "Mrs.Smith".
Aug.13,1901,Kay Co.,OK.
She lives in Longwood Twp. and I think in the 1900 census, she is in that township in Kay Co. with her widowed mother and siblings-mother transcribed as "Massy",but the image looks to be "Marry";among the children are Arthur and Anna.
The marriage record for Hellen gives a birth place of Kansas, but the census shows Illinois,with younger children of the family born in Kansas.

Thank you SO much! I have looked, and looked, and looked!
