Who was the Dunadan?

Heeheehee, my friend who is always rivaling me for the tittle of bigger LOTR fan (It's ok, I know just jow much I love it and that's all the tittle I need ) can never seem to remember Wingfoot. I constantly ask her what the name the riders of Rohan gave him was at random moments, and no matter how many times I do it, she can't remember it! Heeheeheeheehee...... it amuses me....
