I work on the Nez Perce National Forest and have a Castle Creek, Castle Creek Work Center and Campground in my area. I happened to be in the District Office in Grangneville, a woman was asking if we had any knowledge on the Castle family. There happened to be little we could help her with but she was headed to the local museum for some information. She also said that there were Castles in the cemetery she was checking. The cemetery is Prairie View in Grangneville and I have seen it online. I would be interested if any of your line has information on the family that settled in that area.
