Hi,
The Boundary County Historical Society, http://bonnersferrychamber.org/members/bc_historical_society... seems to be the source of county records. They may charge a fee to look up and copy pages. I know that any society appreciates a donation.

If they don't have the book, contact the www.boundary-idaho.com/library.htm . Ask them if they have the book and if they'll do a lookup and copy any pages.

You can also contact your local Library and ask for an inter-library loan of this book. They might not lend it out because it's a reference book but it doesn't hurt to ask.

Are you also looking for Census, military and other information about John and Anna. If yes, contact me and see what I can find. Successful Searching!
