Sorry it has taken me so long to get back to you, I was on vacation. I have the names Donahue & Butler on the same stone that was erected by Elizabeth Wedding in plot B107. I also have a Donahue Cook stone in plot B135. There is a Lawler stone beside it in plot B134. There is a LeFrancois stone in B119.
There may be more, I have not completed the cemetery yet. If you give me your email address, I can send you photos of the stones.
