Hers is closer to mine, it sounds like!

I’m “AHN-dree-uh,” not “AND-ree-uh” or “Ahn-DRAY-ah.” (I suspect that your sister is the last one.)

I was born in France (to US parents), and they didn’t quite give me the French pronunciation (more like “OHN-ray-ah,” with almost no audible “d”), but mine is definitely not one of the top two US pronunciations.
