Most unusual nicknames (based on a child's actual name) that you know of?

[Bagging]

What are the most unusual nicknames, which are based on a child's actual name, that you're aware of?

And how do you get schools to use nicknames instead of official names? Surely they have to teach children to use their legal names?

My kids called Edith, friend of mine wanted to nickname her Ithie-Louise (Her middle name is Marguerite)

I once knew a William who was known as Liam. I considered them to be two separate names but he insisted it was normal (like an Elizabeth being known as Beth - which I also find a bit odd).

Nothing odd about William being known as Liam. Or Elizabeth being known a Beth. It's just dropping the first part of the name.

I've taught a Lolly who was Lauren.

I met a puppy called Peggy today!

surname Milligan often leads to Spike as a NN

surname Souter gives you Soapy.

I worked with a very posh woman called Flossie. Her actual name was Charlotte and she spent a lot of time trying to convince NHS IT to change her official email address to flossie.surname rather than the Charlotte.surname she had been allocated.

Toffee for Dorothy based on how her older sister pronounced her name.

Lad I knew was known as Cupcake.

I don't know his real name...

I always wondered what Flossie was derived from.
My mum occasionally talks about a Flossie she knew when she was young except Flossie was old then, which would mean she was probably born around 1900. If that makes sense.

Is Flossie from Florence? I thought it was. Could be from Flora.

Where I work, how we refer to a child often differs on paper to verbally. If a child is known an a diminutive we always use it verbally but only on reports, emails, certifcates etc if it is included on the school system in brackets next to their full name. If there are no brackets then they get called Constance, Frederick, Archibald, Henrietta-Maude etc on paper even if they have only ever been called Connie, Freddie, Archie and Hetty out loud.

Nicknames that bear no relation to the child's name or derive from their surname would never be used by staff - except the Sports dept.

Sometimes children are known by their middle names only. And it's quite common for them to have a British name and a name from their own culture (in those cases the British name is often quite dated or embarrassing and the child quickly prefers their original name - eg Douglas, Deborah, Audrey, Clyde, Eileen, Einstein, Chaos)

There are some very out there/not name like nicknames which I've never been able to bring myself to use, even if the parents do. Usually because I think it makes a beautiful name ugly or odd:
Karizma nn Krig
Muqaddas nn Muck
Phoebe nn Feebs
Hope nn Hopie
Iona nn Uh-oh

Unusual ones I've come across which do get used by teachers:
Joaquin nn Jimmy
Ignacio nn Nacho
Darcey nn Dottie

(all those examples range from 1 - 15 years ago and from ages 2 - 18 for anonymity).

I have a molly who gets called gladys
no idea why!
she answers to it and nobody has ever questioned it!

We live in France. Schools only call DC by their full first name, no nicknames or diminutives.

This caused us problems when we discovered DS1, aged nearly 3 and starting school in 2 months, didn't know his first name and certainly not pronounced in the French way.

I had always spoken to him in English with a diminutive (e.g. Dom instead of Dominic - not his name) and DH in French but calling him "petit loup" (little wolf).

DH had to only call him his full name for the next 2 months for DS to realise it was his name 😀
