Don't like Dinah (Dinah Dinah show us your leg, show us your leg, show us your leg - awful song I remember from somewhere)
Deanna sounds nice (is it American I wonder) but doesn't have the same feeling to me as Diana.
WegmansCookies Glad you like your lovely name, and am reassured you don't mind it shortened to Di. I still have a problem with later being an 'Auntie Di', to me it's like saying 'Auntie, drop dead!'.
I might be overthinking it ...
