[Facts] Re: The Name Alois
Hi, Shiraz -- and welcome to Behindthename Land! I think the "Alois" that you're remembering from Goldman's play was actually "Alais", and definitely a lovely feminine name pronounced as you said.
The "Alois" that I know of is a masculine name. It is a variation of the name "Aloysius", and is pronounced: "al-oh-weese". The name was spoiled by having belonged to a certain "Alois Schicklgruber" -- who could have spared the world a great deal of tragedy had he been born sterile.
