Is it worth it to buy a baby name book?

I’m seriously considering purchasing one because I can’t seem to find any baby girl names I like on the internet. I keep coming across the same ones.

I’m hoping to find a name that is very unique and beautiful, but not too odd lol.

My father told me that they found my name in a baby book and my name is very very rare. Whenever you search “baby girl names” my name NEVER pops up, ever!
