Samuel Winner is my great great grandfather. His son whose name is George Washington Winner is not listed in the children's list. George is shown in the family of Samuel Winner in the 1870 census. He was 13 at that time and has siblings with the same names as shown on the grave memorial you have put in. I am certain that he was in this family. His info follows:
George Washington Winner was born 15 Feb 1856 at Barry, Pike county IL
He died 15 Dec 1932 at Monte Vista Colorado and is buried in the Monte Vista cemetery.
He married Mary Jane Shields in April 1876 at Barry IL. They must have lived in Ashland IL as they had 5 children born there from 23 Dec 1876 to 7 Jan 1885. They had 3 children born in Mirage Kansas from 17 Jun 1887 to 16 oct 1889. They had another 6 children born from 22 Apr 1892 to 27 may 1901 in the San Luis Valley of Colorado.
