Here's a fun site. It tells you how many people in the US have your name. It also tells you where your name ranks in popularity.
My name is the 8th most popular first name in the country. And of 2,595,183 who share it, 99.77% are males. Who would name their daughter Richard?
So where does your name stand? And are there others with your same first and last names?
My guess is that the data base that runs this thing is going by birth certificates, not nick names.
