What are some good baby name search engines?

[My name Isobel.]

I figured everybody could use a question like this.

I know a lot of baby name search engines, but there some I've seen (pretty good ones too) on here that I've forgotten.

1. What good BN search engines do you know?

2. What good baby name popularity ranking sites do you know? (I.E. Top 100 or 1000 list, etc)

Thanks!
Also, I saw a baby name site on here that someone posted, which I lost. It listed the popularity of names INCLUDING the different spellings of a name and counted them as one name/unit. Does anyone know a site like this?
