Courtney for a girl?

Kay

Is the name Courtney out? Like "too old" and not just it anymore?

My name was going to be Courtney by mom refused. My dad always talked about how if he had a 2nd daughter he would push for the name again. Well, I am TTC and my husband and I like the name. Is it still an alright name to use? Or should we just scrap the name?
