I wonder if there is a web site where you can do some work and find out of any of your relatives were killed. Since I am from Arkansas it would be interesting to know.
Contact these people, they should be able to help. There is a group in Tulare CA that catalogs the descendants of MMM victims.
One of my good friends is part of the group. I can get you more info if you would like.

Only 80 of the 120+ killed are known by name. Bagley’s book has the most comprehensive list of named victims. Most were from around Harrison and Fayetteville... although several had recently immigrated from Tennessee before they embarked for California.
