Is Jemma a madeup/creative spelling?

[Saturday22April]

Is the Jemma spelling one you would think "my gosh" at?

My name is Jemma!!

I prefer it massively to Gemma, most people presume it's a G. I always have to say Jemma with a J

I'm biased but I like it!!

Bumble yes it's a nightmare in America they're like What??? Jemma??? I've never heard of this
