What have you tried researching?
Jews in Idaho during that time period were often called "homesteaders" as
they were the first given land by the United States government. Just
today I was talking to the Bureau of Land Management Office in Montana
which possibly covers Idaha (I was ordering copies of land records for
relatives who were in North Dakota about 1907-19???'s. Have you tried
using switchboard.com looking for anyone with the same surname?
Best of luck, Deborah
