It's not easy being a member of the French nobility these days. The titles given out by royalty have lost their moneymaking power since France moved away from government by monarchy. Consider this: France has more than 30,000 castles, but many of them are in rundown shape because proper maintenance is so expensive. You can buy one for a song and a promise to restore it, but that doesn't help the poor aristocratic scion who inherited it.
By now you are playing music on the world's tiniest violin for these impoverished aristocrats. But they don't need your help. There is a club for aristocrats to support other aristocrats, called the Association for the Mutual Assistance of the French Nobility (ANF) to save the downtrodden elite from having to live within their incomes. The ANF has helped thousands of people, but those people have to prove they deserve it by documenting their lineage and titles, through their father's side only, and proof that lineage all comes through legal Christian marriages. If you jump through those hoops, you might get support, and even an informal dating service so you don't have to marry into the unwashed masses.
