Actually, there are many interesting women who are currently members of GH. In fact there is one in this thread, and you guys completely missed her. Well, she is a girl in high school, so maybe it's better you guys missed her.
Back to the OP, if the guy is not married, I don't think it's strange to look for a girlfriend who is into keyboards. In fact, I have a fantasy of meeting a beautiful woman who loves keyboards, and who is totally swept away by my keyboard collection and awesome clack collection. I think this fantasy is mainly caused by the fact that I'm married to a woman who is rather indifferent to keyboards, and clacks. But, in her defense, she pretends to understand my hobby, which I guess is something. But she still complains that they take up too much room, which TBH, they do at this point.
Anyway, I hope the OP finds a nice Celtic girl who loves keyboards. And hopefully she speaks French. But asking other GH members to direct their sisters your way is totally skeevy.
