John was a brother to my grandmother, Grace. I believe their parents were Peter Siler and Mary Frost. In a letter I found it lists Alex and Nelson Blair of Sioux City, Iowa as her half-brothers and Lee of Des Moines and Clarence Blair of Sidney, Iowa. Grace was born in 1888 and died in 1931. I believe John died in 1944 in Des Moines. I have his obit somewhere.
