Katie Perry ? Mark Teixeira? that's stretching it . they may have some Portuguese ancestry but are far removed from it.
Never heard of the first two, and although I've heard Teixeira's name I don't know that much about him and wouldn't be able to recognise him.
LOL that was only in Canada. Sorry, I mean that was only in Ontario Sorry, I mean that was only in Toronto Sorry, I meant that was only within the Portuguese community in Toronto.
Vasco da Gama. He is known (and will continue to be known) by many people from India, and you know how few they are. No one will care about Mourinho, Eusébio, and Ronaldo within 200 years, just like no one cares about any great gladiator from the 1st century. Fernão Magalhães is a good candidate too.
