Buried in Marengo Cemetery, Liberty Township are your two John Thompsons:

There are several Mary Thompsons buried in this cemetery also and a Martha Thompso

I find NO Mahala Thompson listed in the index she may be buried in an unmarked grave or her name was Mary.

One Mary died in 1955 age 77
another, Mary Lee Thompson, died in 1932 age 37
Martha Thompson b. 1889 d. 1949 age 66

The listings in the book are alphabetical, so I can't tell you who is buried with whom.
