Well, I had a very annoying coworker named
Aaron, but I
LOVE the book East of
Eden (just visited the Steinbeck Center in Salinas, CA a few weeks ago, in fact), so
Aron gets my vote.
Aaron feels more biblical while
Aron (to me, at least) feels like a literary name. If not familiar with the book, others might see it as a modernization/streamlining of
Aaron.
I do pronounce
Erin and
Aaron the same, which made for some funny Abbott & Costello style mayhem around the office when we would discuss coworker
Aaron, other coworker's pregnant wife,
Erin, or a competing firm in our industry which is ALSO named
ERIN.
