Try
www.findagrave.com it is free,and there are other sites,just go thru each one.Also back then I believe
Montana was a territory and not a state and he may of been taken to
THIER nearest hopitol (1872) so find the place with that they would take him if sick or injured and start there.For example many records were destroyed in
Montana I believe in
Livingston,but proof of birth of my grandmother was destroyed in that fire.And the book I am speaking of ,just ask your local librarian.Tell that there is 3 volume set in Olympia,washington.
