Warren Craig was granted a land patent 11/17/1884 on the NE 1/4 sec 21 twp 119N rng 061W 5th PM Spink county, South Dakota
He died in Minnesota in 1890. His father, Sylvester, died at Frankfort, Spink county, South Dakota 19 Dec 1887. I could not find a burial for Sylvester.
Warren was the youngest of 8 children. He and Flora had a son, Benjamin born 1879.
I am too far away from Spink county to be of any further help.
