Hoxsey Family Genealogy Forum
The Hoxsey family were pioneers of Spokane County. Some married into the Spangle family that founded Spangle, Spokane County, WA. You need to see if you can get the following book inter library loan.
Gateway to the Palouse, by Nona Hengen, 5th Edition. Make sure to request the "5th" edition, as it has wonderful pictures and genealogy of the Hoxsey family. I'm sure your family must be a part of this group.
I know that this book is at the Spokane downtown library.
