There are definitely unique baby names that will be tough to find on necklaces, key chains, and bookmarks for the child in question. I knew a girl named Hayle-Leigh (pronounced like Hayley) growing up who could never find her name on anything! When it comes to celebrities, the names can get even more unique: Apple, Audio Science, and North West come to mind.
None of those names compare to Elon Musk's son with musician Grimes.
