Welcome! Funny I find a message about the name Sarah because I've been thinking about it a lot recently. I have never really loved the name Sarah, until I met my mother-in-law who was, you guessed it, also named Sarah. She's a really sweet woman, so the name kind of grew on me and now I think it's lovely! I'm expecting, and I recently found out I'm having a my very first daughter (out of 3 sons), and for the absolute longest time my husband has been begging me to name her Sarah in honor of her, and I just might.
As for the name, I think it ages like fine wine. I don't think you should change it. It's sweet and, although overused, it's a classic.
