Here's a Distinction
Emilio Marcos Palma, born January 7, 1978, was the first person born in Antarctica. According to Wikipedia, he's the only person known to be the first person born on a continent, and also had the southernmost birth in history. How'd you like to be that guy? Palma was born at Argentina's Esperanza Base, which is slightly more southern than Chile's Eduardo Frei Montalva Station, where two Antarctic children were born in the 1980s.
Personally I've spent a minute or two as the southernmost person in the United States, during a 1996 trip to Ka Lae, Hawai'i, and another couple of minutes in 2003 as one of the two northernmost persons in Mexico, when my friend Mike Benedetti and I visited Los Algodones, Baja California.
