Edgar E. Bush was my Great Grandfather on my mother's side. His first marriage was to my Great Grandmother, Ada J. Knox (b. 3/12/1884 in Kansas) in Malheur County, Oregon on May 10, 1901. They lived in Ada County Idaho (in Boise).They had one daughter (my grandmother), Edna Letha Bush: Born Boise, Idaho 12/10/1901.
Ada died in Boise 2/14/1903. Edgar remarried Mamie M. Krieg in Boise on 4/2/1906. As far as I know, they had three daughters, Meda Eddy of Sonoma,CA, Mary Brown of Whitmore, CAand Inez Green of St. Helena, CA. Edgar died in Boise on 12/10/1914.
Hope this helps. If you have any more information about Martin P. Bush I'd appreciate it.
