Haaris is a good choice because Americans pronounce it "Harris". That is my nephew's name.
My brother married an American too, who converted and makes a great member of our family, better muslim than me, too!
I am from Washington DC also, ashmughal, grew up in Potomac and Gaithersburg, went to UM for Engineering and moved to Detroit 20 years ago to chase a dream to design cars.
Good luck and congrats! Three's a charm. I have three girls, I know.
