I lived in DC proper for the majority of my life (ie the actual city) and I worked at a church with a preschool. I saw at least four or five Oscars - I merely wanted to make the point that the name is usable and being used.
As for Washingtonians having good taste...that depends on which area and which demographic and just the person in general. If/when I'm back in DC I'll post a list of names from our
Summer Camps (I worked at a church and my dad runs a non-profit). It's fun to see all the different names - the international names from embassies, the yuppie nams, the kreativ names...only reason I didn't mind doing data entry once in a while.
