is the surname bernard the original surname of the dauterive family
I am searching to find out if the surname of Bernard is the original surname of the Dauterive, Valliere, and Dubuclet families. I know that Jacques Bernard Dauterive had three sons, Jean Antoine Bernard Dauterive or de la Hautverie, Joseph Bernard Dauterive de Valliere, and Clair Bernard Dauterive Dubuclet, and since the name of Bernard shows up three times and the name of dauterive translates into de la hatuerive, the name of valliere is de la valliere and it is a title, and the name of dubuclet is also a military nickname, any information would be greatly appreciated,
