Dumbledore loved his parents very much, but hooooo boy were they a source of some angst. His dad went to prison when he was ten for attacking/possibly killing a bunch of teenage boys who'd brutalized Dumbledore's sister, and he died while serving his time. His mom died when he was eighteen when his half-crazy sister accidentally let out a burst of magic that struck their mother, leaving Dumbledore in charge of his family.

It's never stated if Italy had any parents in canon (though I think there's some fanon theory that the Byzantine Empire's his dad?). And since nations' families don't work like normal ones, he may not have had them. But he definitely had Grandpa Rome, whom he adored. If you ask him, easily his most happy and content years were during the time he spent traveling with his grandfather (which also coincides with the Renaissance).

V doesn't remember anything earlier than his test subject days, so...yeah.
