brian in hebrew?

That's no great surprise as Brian is not a Hebrew name, and the BR sound doesn't really exist in Hebrew, you'd say/write it as a B and an R but they would be separate, like in Baruch (which means blessed). Probably, hmm, Beth Resh Aleph Nun with an "ah" sound vowel under the Resh and an "ee" under the Aleph. Pronounced: Buhraheen. Not what you were looking for, I'm sure, but that's the way Hebrew rolls.
