I believe Mattilda Lacourt is buried in an Allouez cemetery, which would be in Brown County Wisconsin Lewis/Louis Destash/Destache, Destiche/ there are many spellings of the name Destash, though I believe most pronounced it DES-TASH. Her spouse is in the Fort Howard Cemetery.

I don't know the Lebeau family. I do have some of the LaCourt's in our tree, but most of the time it is because of marriages to other family members. Destiche/Distash is a line in our tree as well.

Enjoy your visit!
