Do you have any references / sources / examples / stories of this? Sounds like an interesting area.
Thought there's a difference in being disowned / disinherited, and in simply not being the primo genitur -- the offspring who will inherit the title.
I'm thinking of Ludwig von Wittgenstein, born to one of the wealthiest families of the Austro-Hungarian empire in the late 19th century. In his case, he chose to leave the family, or at least its wealth, though AFAIR it remained reasonably supportive of him. I'm not sufficiently versed in nobility/royalty to think of other instances offhand.
