Gilbert fits the trend of grandparents/ great grandparents' names that are returning. I think it's a bit geeky, but that's me.
Gil or
Bert work better than
Bertie.
Bertie reminds me of
King George VI.
Johnny Depp played the title character in What's Eating
Gilbert Grape, and there was a Packer named
Gilbert Brown for namesakes.
Julio- I think that in the US at least,
Julio is too closely associated with
Julio Iglesias. The image I have of a
Julio is a romantic Latino singer trying to sweep someone off their feet.
