I think your serious B/B and G/G sets are too matchy in the NNs. And I think I would prefer Jim(my) or spell it
Jamey. But that's just me.
Anyway, they're all really nice combos, I'm assuming the only difference in Serious and Not Serious is family names?
I especially like
Charles Frederick,
Charles Llewellyn,
Eleanor Margaret and
Margaret Evelyn.
