As you can see from the map, the last name of Lundquist is most common in Sweden where 240 of every million Swedes share that last name. This was lower than I expected considering Lundquist is a Swedish name.
Changing the spelling to Lundqvist (the proper spelling of my maiden name according to my advanced calculus professor) gave results closer to what I expected.
In the United States the top city for Lundquist is High Ridge, Missouri. The total population for High Ridge is only around 4000, so High Ridge might have beaten out all other US cities with just one listing in the phone book.
