I really love the name [name]Andrea[/name], but it has so many pronunciations. Some say ON-dree-uh. Some say On-DRAY-uh and some say [name]ANN[/name]-dree-uh. I like [name]ANN[/name]-dree-uh the most. Also do you think this name is out of style?
I don’t think so - maybe more popular in the 80s but definently not dated (in my mind). I pronounce in [name]Ann[/name]-dre-a because that is how a friend of mine says it - and I think it is the most common . . . .it’s one of those pretty girly names!
I don’t think it’s dated. It’s pretty enough that giving it to a baby girl would make it feel fresh and new.
As an aside: [name]Andrea[/name] is the name my mom wanted to give me, but Dad didn’t like it. 
I would think that 99% of people would use your preferred pronunciation of [name]Ann[/name]-dree-uh. I think it’s rather pretty and not dated at all.
