Seili - when I was a teenager we lived in Calgary, Canada, in a neighbourhood that was predominantly Middle Eastern immigrants of a variety of religious backgrounds. I realized after re-reading your post that the name I'm thinking of, "Nahum" or "Nehum" is a little different - it was always pronounced Nay-hum or Nay-hem, so it didn't rhyme with Liam. I did look it up, though, and the name I'm thinking of is still derived from Nehemiah.
As an aside - I have a good friend name Emmis, which I think is lovely/has nice mouth feel/decent nicknaming potential.
