Now don't take this too seriously, they readily admit that the accuracy of this thing falls between a Magic 8 Ball and taking 300 million surveys. I can say for sure it is not bang on because I just ran some family member names, and at least one aunt's name came up with zero people in the USA having that name. I just spoke to her the other day, so I imagine, unless she was recently abducted by aliens, it is not 100 percent accurate. Have fun with it.
All the best,
