The book I am speaking of is easy to get a hold of,it was for me anyway.Go to your local library and ask for They gazed on the beartooths by Jim Annin.I am in
Oregon and thats all I did.The books came from Olympia,Washington.I will say that you should check the cemetaries in
Carbon Co.You can do that with
www.findagrave.com it is free.If you find nothing there try USGenweb for Montana.Or Genealogy.com,just type in the surname and see what you get under John B.There will lots of them but maybe you find him in there.I would have to send for these books again to tell you right out.My Grandmother and Mary were friends maybe John B was a relative to Mary?
