Here from browsing the next-gen-fest friends list (and procrastinating horribly on my own fic...) I have to vote for Fred II! Of all the "namesakes," I think he's the one with the most interesting backstory. I'm guessing a *relatively* large number of people get named after their grandparents (dead or living)--much fewer are named after their parent's late twin. While I imagine George and Angelina had a very healthy, happy, marriage, I also headcanon Fred as having a lot of struggles trying to carve out his own identity and escape his namesake's shadow. So although I think he probably had a longer journey to make space for himself, that just makes the narrative more interesting, and whatever life he settles into all the more rewarding.
