The grace is part of a plot of 4 graves owned by W. R. & Una Maschner. In the first grave is Alberta Milkintas who dies in 1957. The second grave is empty, but it says it is reserved for Vince Malkintas. The next grave holds my greatgrandpa Jay, and the 4th one is empty.
Of interest is that W. R. & Una Maschner were living in Arizona in 1957 per info on ancestry.com:
Name: Una Maschner
Spouse: William R Maschner
Residence: 1957 - Phoenix, Arizona, USA
I will have to do more digging to find out why he was buried way out in Lemont, and who the Maschner's and Milkintas's are.
