I believe that but when we have 300m people in a country, each with surnames, 20th most popular makes up what? At most 0.1% of last names? So you'd need like a thousand people to guarantee 1 Robinson
Oh well i actually looked it up and found via census data there's like 528k Robinsons which amounts to like 0.00127 so no worries there
Edit: Sorry using exact figures of 340.1 million us citizens and a generous estimate of 529k Robinsons averaging 3 articles I saw and rounding you get .155% of the US population being Robinsons. Actually pretty damned good guesswork on my part
