I have a puzzle I need help with. 1920 Plattsmouth, Cass Co. census shows Donald C. Warner as the son of Charles H. & Barbara Warner. Familysearch shows Donald Charles Warner as the son of Frederick Marion Warner (a son of Charles & Barbara) & Donald's mother as Bonnie M. Robinson. I realize that Donald may be a grandson of Charles & Barbara. Frederick died in 1928, but I can't find any record that shows Frederick, Bonnie, & Donald as a family. Donald was born 19 July 1911 & died 19 July 1938. I don't see any way to sort this out except with an obit on Donald or contact with any descendants he might have. Anyone have any info? Thanks, Kris in IL
