My SIL has a sister named
Laura, and it is pro. LAH-ruh. The rest of the time it is pronounced lor-A (that's the best I can do.)
Lara is pronounced a few different ways here - lare-a and LAH-ruh. I actually prefer the first one because it's what I'm used to.
A good example of
Laura being pronounced LAH-ruh is in Sleeping With the Enemy
