Whoever visits the various forums on heraldry or is in any way involved with chivalric institutions will invariably end up reading/hearing about someone’s claim to Polish nobility. Be warned that more often than not, the claim is completely false.
What’s especially interesting is that they’re not content with claiming minor Polish nobility but go to the top, even claiming princely status.
Rafe Heydel-Mankoo, co-editor of the venerable World Orders of Knighthood and Merit and recognized expert on such matters, maintains a site on Polish Aristocracy that lists those families that actually are titled Polish nobles.
