The Welsh win again

According to the Census Bureau, who should know, there are a bunch of Smiths in this country, some 2.3 million.
However, there are a million and a half people named Williams, 1.3 million people named Jones (including members of my own family), over a million people named Davis (which is really Dafys and thus Welsh) and even over 750,000 people named Wilson (my middle name, which is Scottish or Irish in origin and, given all the redheaded cousins I have, logically so).
Thus, out of the top ten surnames, four are Celtic, two are Hispanic (Garcia and Rodriguez) and the rest are English (Smith, Johnson, Brown, and Miller).
We win.
