When I have a baby, I plan on naming my girl this. I love how its a little unique but not weird, it's strong and it's not one of those cutesy names that they sort of grow out of. I would pronounce it an-dree-uh. Not an-drey-uh. I don't like that as much. But they are both beautiful names. I also like how it's a strong name, but I dont' agree with manly myself.

My name is Andrea! I pronounce it an-dree-uh. I get called every version though! on-dre-uh, an-drey-uh, ain-dree-uh (ain't without the t). You kinda get used to it. I even get called Angela or Amanda once in awhile! For the female version it means womanly.

I also pronounce my name And-ree-uh. It's a good name, and lots of fun nicknames can come from it. (My friend recently started calling me Android. Haha. I love it.) But yes, I do often get called Angela or Amanda. But not as often anymore.
And my middle name is Lauren! Which I though was slightly funny, as Andrea and Lauren commented on this one. Both beautiful names!
The first meaning I saw of my name was "valiant and brave" however, not "manly".
