Name idea for nickname JJ?

I am due in a month and we can’t agree on a name 🙈

I like the nickname JJ but can’t think of any names it could be short for.

Would love some ideas! 💗

I like uncommon, pretty, earthy names.

Names I like (but can’t have due to friends and family or because it’s been rejected 🤪): Jadie, Jess, Jocelyn, juniper, jasmine, Jaime

Names I don’t like: Jennifer, anything that sounds like Julie/Judy, Josephine, Joanne, june, Jill or Jane.

(I’m in the UK and they are all fairly common/old fashioned names here for my aunties and mums friends etc)

I’m considering jean as a middle name but I don’t think my partner would agree. I’m not telling him about JJ idea until I’ve got some good suggestions as he says no to everything 😂
