I find this sort of thing fascinating.
There are 1.4 million Americans with my first name and 332 with my last name. That makes my last name the 75,677th most popular. I only know of eight from my immediate and extended family.

I'm not sure how the programme works but it seems to be multiplying the odds on combination of first and last names. Apparently, one in ten will get a 0 response.
According to this method, there are only 2 of me.
