I beleive the cathedral referred to is the Notre Dame Cathedral in Montreal, Quebec, Canada. I am descended from the Tessier family & shortly after WW2 a lawyer in Montreal circulated the family looking for donations to supporta claim against the church for recovery of the land on which the cathedral stands today. Apparently there were not enough "takers" & the claim came to nought. I do not know the name of the lawyer or have heard nothing further. For the next few weeks I will be in Florida & can be e-mailed at JKAMLEV7@Sunline.net.
