I’ve bumbled around on the french genealogy website archives.cotesdarmor.fr and I think I’ve managed to locate Louis Rolland’s birth certificate.
It helps that he was born in a tiny village, St Gilles les Bois, as you can only browse chronologically by year. His father is listed as Jacques Rolland, 34, occupation menuisier (carpenter) and his mother Marie (le) Huerou.
Interestingly, I have discovered a Canadian immigration record which could possibly be that of Louis (on his way to Chicago in 1912) and his occupation is listed as Carpenter on that.
Here it is
I also searched the Genearmor website his parents http://genearmor.cotesdarmor.fr/moteur/
