Sometimes it's not the question of who your father is, but who back your claim to the throne. Kings and princes always need to form personal connection with nobles in the court to gain their support in matters of the state, and in return award them with title, land and power. As long as you manage to keep the close circle happy they have no reason to rebel against you, and they'll put their trust on your heir to honor this system. Not to say the status quo can't be changed; rebellion and usurpation happened all the times even in countries with long hereditary tradition. When the nobles dissatisfy with their monarch and see some other person, or other political system, as a better alternative, they're willingly to revolt (look at the English Civil Wars and Glorious Revolution as examples).
