I thought of it after I sent my last message, but if Paul was still living after Pierre passed away and if, as you say, he was buried by one of his brothers, then that brother must be Delphis. Do you have any information on Delphis and his whereabouts? The only information I have on him is that he married Marie Olive Rivard-Lagranderie in 1870 at St. Guillaume d'Upton and a note questioning whether he may have resided in Boston.
I would certainly appreciate whatever information you have on Pierre Eno & Melanie Latour's descendents (and his siblings, etc.).
Bye for now,
Steve
