hmmm... I will try another angle.. rather than say what I like and don't like I'll tell you what characteristics I think of for a child with that name.
(I once came across a book that polled people in this way about thousands of names and I thought it was quite interesting!)
Dexter - a bit nerdy, wears thick rimmed glasses
Elias - arty, creative, likes drawing or music
Elliot - cute kid, adorable and happy
George - just your average kid. doesn't excel at anything but also does ok at most things
Harrison - clever, popular, will definately go to uni. might even be quite good looking
Orson - probably a bit on the chubby side
Oswald - for some reason I'm expecting this kid to have a crooked nose???
Reuben - likes sandwiches. LOL
Rohan - slightly defensive kid, doesn't make friends easily
Rufus - has shaggy hair, bit of a hippy, probably smokes dope
