How do you pronounce the french name Jean ea in English?

In fact you don't pronounce the "ea" you pronounce the "ean"... but I can't find a Word in English that sounds like it. In English you always pronounce the "N". When you say a Word in "AN" like americAN the emphasis is on the "N" at the end with your tongue touching your teeth. In french when there's an "A" or an "E" beforethe "N" it changes the sound. It's very hard to understand without hearing it and it's hard for me to explain it because my English sucks. I hope I helped you a little.
