interesting astronaut factoid

In my recent box of memorabilia Dad sent me there is a decanter/pitcher featuring Apollos 11, 12 and 13 listing all their names.
I'm in the kitchen cooking and just happen to look over at it.
It was turned to the Apollo 13 side facing me.

I never knew any of them, much less all 3 of them are Jr. (named after their Dads of course)
What would be the odds on that?

Anyway, I just found it to be a neat little obscure factoid.
Wonder if that's a question in Trivia Pursuit.
Not likely - way too obscure unless you're into space flight history stuff.
