I have mixed feeling for the name because my brother is
Colin Andrew but he's always been "
Andy" and it sounds strange when anybody call him
Andrew and never
Drew.
You're right, most Andrews nowadays are called "
Andrew", whereas Andrews my age (20's) and a bit younger were mostly called "
Andy". I used to not like
Andrew very much because the Andrews and Andys I knew were annoying little kids who turned out rather badly (except my brother, perhaps because he's
Colin Andrew? joking).
I've heard of very few Drews, I like "
Drew" but mostly
Drew reminds me of the popular "cool" guy in school who became a doctor or lawyer (
Chad has a similar image for some reason). I never think of it as a girls name.
So I'm not surprised
Andrew is still popular, it's a handsome and strong Biblical name and there's been many influential men named
Andrew throughout history. And boys named
Andrew today can just be "
Andrew" without being worried that they might be called
Andy or even
Drew unless they want to be.
