Here is some interesting information from the US Census Bureau. First the 30 most common male names. The first number is the actual percent of males in the US who have that name. Second number is the cumulative percentage adding from the top of the list. (Thus you can see that the top 12 names account for 25 percent of the male population.) Finally, the ranking.

  JAMES          3.318  3.318      1

It looks as if Jose, #28, is the only name that doesn't originate in the British Isles. (I'm not sure about Jason and Anthony.)

You can see the (sort of) complete lists (1000+ male names, 4000+ female names, 88,000+ surnames) at http://www.census.gov/genealogy/names/

I'm not sure what the criteria were for inclusion, but it looks as if they wanted to cover 90% of the population.
