I'm surprised that George R R Martin doesn't show up for Santa Fe. Surely he's more-googled / wikipediaed than Murray Gell-Mann?
I think it has do with how they're pulling the data. GRRM doesn't seem to appear on the wikipedia category page for people from Santa Fe: https://en.wikipedia.org/wiki/Category:People_from_Santa_Fe,...
Edited 2015. So they must not have pulled this data.
