The PDF documents below contain 60000+ names of popular celebrities allover the world.
I took my time to arrange everything in systematical order and by gender. SEE FOR YOURSELF.
Note: Only those top names on each box are by gender. The rest of the names on that same box are mixed which makes some of the first set of names to appear twice - but that shouldn’t be a problem, just focus on the first names.

Letter system for words you are unfamiliar with is one of them. You can use it for zip codes or even general codes in stores and such. You can also use it to build up other systems like a binary system. You can easily turn it into an 8-digit binary system but 9- and 10-digit systems are also possible (though 10-digit needs a little expansion of a standard alphabet system). You can turn it into 26 memory palaces with 26 loci each.
The possibilities stop where your creativity stops.
