Need a longer name to be shortened to Mollie.

[Mustardnowletsnotbesilly]

35/40 Bump is called Mollie which we like but I want her to have a name that we can shorten so her nickname is Mollie. I'm not sure Mollie is very professional for when older.
I can only think of Margaret which I'm sure about.
TIA

Bishy yep, story of my life.
I don't understand this 'options' thing.
My name is like a Jennifer, but Jenny for short. So all my life I've been called Jenny, and asked my mum, if you never planned on EVER saying Jennifer, why call me it? Why not just Jenny?
She said it was just the 'done' thing to have a proper name.
I use Jenny on everything. My CV, my work email address, all Jenny. It's my name, what I've always been called. Your name is just your name? Why do you need 'options' with your name?
And, if someone really hates their name, there's always deed poll

She was born three days ago. Didn't look like a Mollie. She was born with a huge amount of dark hair so called her Scarlett...

Thanks for all the advice though!

Mustardnowletsnotbesilly Congratulations! Scarlett is a gorgeous name
