I just wanted to add that there is no "correct" way to pronounce Eva as you can see. I grew up watching "Green Acres" reruns so I had always assumed Eva was pronounced AY-va (as in actress EvaGabor who was born in Hungary).
FYI, actress Susan Sarandon has a daughter named Eva (EH-va). Eva's father is Italian. Also, Evelyn is pronounced EE-ve-lyn in England, I believe. Someone correct me if I'm wrong.
Anyway, no matter the pronunciation, Eva's gorgeous. Excellent choice.
