Thank you. Several folks have pointed out the Wallet=de Vallette thing. That is possible. Clerks have come up with much stranger things when recording names - esp. foreign ones!
The question I have for you is "Bernard is said to have married three times" - where? Not in any of his official biographies that I have found. The only title I remember off the top of my head is Leo Mouton's _Epernon of Old France_. Mouton lists two marriages in France but shows no children born outside France and no third marriage. I would love to hear that someone has found that marriage!
