Annie short for...?

[RunningOnHope]

We're not keen on double first names like Anna-Maria but looking for a nice way to have Annie as a NN.

DD1 has a longer name and is exclusively known by the NN so hoping for something similar. Any ideas?

Anne. I'm an Anne. Is definitely nicer and more unusual than Ann. However, I have experienced a life of it being misspelt as Ann.

A PP has already suggested it, but another vote for Marianne. So beautiful
