I like it pronounced EEV-lin, especially on men - it makes me think of Evelyn Waugh. I do think it's a shame it's this popular. I've never met one, though, as I don't live in an English-speaking country. Hmm... right now I'm feeling Evelyn Clarice (EEV-lin KLA-ris, just to he contrary) and Evelyn Ambrose.
