I wouldn't say Sally was a favorite, but I like it much better than Sara or Sadie. It's cute.
Sally Ann is often used as a nn for the Salvation Army so I wouldn't use it. Sally Jo, Sally Rae, Sally Jean, or Sally Marie would be my choices if I wanted a Sally combo that would work as a double-barreled name.
Before you criticize a man, walk a mile in his shoes. That way, when you criticize him, you're a mile away and you have his shoes!
