Looking for Frederique Bach

I am trying to find an old friend from LePuy en Velay.  Her name is Frederique Bach.  I did a French exchange with her in about 1990, she would have stayed with my family in Sutton, Dublin, Ireland. 

At the time she was friends with Max Mejean, Florence and had a boyfriend called Jean.  If anyone has any information please email me.  I would really like to get back in contact with her.
