Thank you for your informative reply! In answer to your questions:a Ruth Palmer w/the Edward Palmers on 1920 Census,
is not related. (FYI: Edward, Ella & Claude came to Idaho c1916 from Kingston, Missouri.)The Claude Elmer Palmer who died 1988 in Oregon is NOT our Claude.
OUR Claude was not mentioned as one of the "survivors" in his father Edward F. Palmer's obit in Idaho Falls Post Register,7 Jan 1942. In his mother Ella Palmer's obit from Kingston, Missouri 9 July 1958 states that her husband and "adopted son, Claud, preceded her in death." So, I'm thinking Claude died sometime after the 1923 land grant (which I've copied)and 1942 when Edward died.
I didn't look up Edward Palmer's land; he was probably near Dubois, where he operated the grocery store and state liquor dispensary. I did,however, look up John Palmer, Edward's brother who had come to WA then on to ID in early 1900's. Found a 1915 land grant to him and that may be where the name Palmer Springs came from. John's 80 acres and Claude's 160 acres appear to be near each other. John Palmer (Claude's uncle) was killed 4 July 1919 when he was thrown from a horse in a bucking contest! John's obit mentioned brother Edward and said John was "prominent business man and stockraiser of Dubois...he w/William Garrison was erecting a substantial new theatre building in Dubois..."
I can't find any Census records (after 1920), marriage or death record for Claude. Do you have any suggestions of where to turn next???? Thank you. Grammy Ann in Issaquah
