http://www.localnews8.com/news/28467650/detail.htmlI've seen several postings for people looking for relatives buried in Blackfoot at what was once called the Insane Asylum. The above news story discusses a goal to erect headstones for the more than 1000 people buried there, of which only 20 have headstones now.
"Hospital administrators and staff are on a mission to change that. They're looking for monetary and material donations from the community to put headstones on 982 plots and build a memorial for the 40 without a recorded space."
