I love the name Issac Jacob, but spelt like that. I don't get the two A's in the traditional spelling.
However, I really want to spell it the Arabic variation which would be Ishaq but spelling it the way it sounds, Izhawk Jakub. Is that too weird his dad doesn't like it because he doesn't want him to be made fun of, but I love it spelt like that.
I feel like its unique but not way out there since I'm Arabic
