Oh, and I love, love, love the nickname Nye for Anuerin. In fact, don't use it, I'll use it if this baby is a boy. Shame I don't have a good Welsh surname like Williams really. And it would probably help to live in Wales, from some of the comments here!
As for the others, well:
Blake Williams: I'd say he was born in the 70s.
Edward Williams: Biased, as I love the name Edward. I always imagine him to be tall, a smiler, with brown floppy hair.
Morgan Williams: Personally I think of Morgan as a name that could be a girl.
Reid Williams: I prefer traditional names, and I regard Reid as a surname
Anuerin Williams: I think I've been clear on this one!
Frank Williams: I know several Frank Williams, and they are all in their 40s
Gene Williams: a tap dancer with silver hair
Alistair Williams: I like it, timeless.
