Need names that work in France, Wales & Ireland

[Machin]

Any ideas? We're struggling.

These all work for France, I think they work in Wales and Ireland (my Irish heritage not as strong as my French) also but feel free to correct me.

Clara
Melissa
Juliet
Zoe

Max
Adam
Louis
Eliott

My English daughter with a Welsh dad is Annie. I'm a French teacher, this is a popular French name and myself am the daughter of an Irishman, it's a family name in this branch of the family.
