Baby name is a copy cat...

Alright, I might be being petty or silly but this is my dilemma:

My boyfriend and I have liked this specific name since my son was born. It was our girl choice but of course we had a boy. Fast forward 2 years later we are expecting baby number 2 and it's a girl. Within a month of finding out the gender a girl I graduated high school with names her baby the same name. I dont even live in that area any more, we arent friends just acquaintances, and if we do move back home we wouldnt live close enough for our kids to go to school together. It only bothers me because several friends I've told our name to are immediately "oh didnt such-in-such name her daughter that?" I need reassurance that I'm being silly and if we like the name that's all that matters right?
