I know a physical therapist that works at Our Lady of Lourdes in Laffayette. She's from Belgium and still has lots of family there. Email me if you need her email address.
Thanks, Billy, but I'm not sure that would help. I finally did hear back from Yves, although nothing about contacts, and I have another friend in Belgium who says he's "finally using this assortment of business cards for something", so we'll see what happens. :) It's sweet of you to offer, though! Oh, but if she thinks her family might like to see some Cajun music, pass my e-mail address along to her and have them e-mail me for any dates we might actually set up.
