Try this address: St. Peter's Cathedral, Diocese of Marquette, 444 S. Fourth St. Marquette, MI. 49855. They not only have St. Peter's records but they have the records of the French Church that was torn down. St. John's. Write them and give them as much information as possible, they will research a couple of years either way. They have been very good. My family came from Marquette and their records are there. Some of the real old ones are in Latin. I have some old Catholic burial records here that I collected years ago. I will look through them later for your names. The bodies that use to be buried by St. Peter's church were moved many years ago to make room to build in the city. They were moved to the edge of town. It was called the Old Pioneer Cemetery. When my mom was alive they were going to bulldoze that old burial ground(1980's) but a bunch of us ancestors went to court and contested it. It's all grown up now and no one can find their ancestors but atleast it did not get bulldozed. Her great grandmother is buried there. Most of these people were of a French/Indian admixture. It would not hurt to send the church a donation for their efforts.
