I prefer it as a mn, too. It just seems to flow better. But is it just the appearance of the "ch" that you dislike? Because Emmerich sounds exactly the same as Emeric.
According to BabyNamesWorld: Elrich = EL-reech Adalrich = AD-ahl-risch or AD-ahl-reech Friedrich = FREE-drich Emmerich = Em-uh-rischSo because of the confusion there, I prefer the French spelling Emeric.
Oh, that's weird. I've always pronounced Emmerich "E-me-rikh," which is the pronunciation that BtN gives. I'm not doubting you or creating an argument or anything. That's just how I've always pronounced Emmerich. Emeric just looks unfinished to me, but no biggie.
I'm confused about it too, and normally I might agree with you about Emeric. But I associate it with Alaric in my head so I see it differently (if that makes sense!).
