While I noticed you included Joshua, for I believe that was another name for Jesus. If so, that reduces it to 1.25% doesn't it? Or, how would you figure that?
I included Joshua because it was on the list and happened to meet your test. Allowing Jesus to have two names double’s his chance of meeting your numerical criteria at least once, but that’s not what happened.
This is a
very poor simplification and you shouldn’t use it, but one could back-o-the-envelope say that if any random English name was given to a baby, it has a 2.5% chance of meeting your criteria. If the person has two names, then that is a 0.0625% chance they’ll
both meet your test.
Remember though, as I understand it, Jesus and Joshua were quite popular names. Joshua is #3 in the US for boys today; that hurts your case.
It is unexpected that the both names would meet the same test, but Jesus does have many titles. This site lists 144 of them:

I’m not typing all those in

, the other list was just a cut and paste from a government web site.
Of course I noticed you didn't have Lucifer either?
As Jim keenly observed, it seems not to be one of the top 1000 names in the US…. But Nick is there

(again Satan, or the minor demons with which he is sometimes equated, has 333 names, according to another site,
http://www.luckymojo.com/esoteric/religion/satanism/demonlist.tn).
It kills me to add to this sort of playing with numbers to find significance, but, objectively, that is what you’d get. To be clear, I’m not sympathetic with your case here, Iacchus. It’s way too easy to find meaning where there is none. Seems to me to be a uniquely human addiction, and I share it with you, in a way, in my love of playing with numbers, but that’s where I end it and where I think it should reasonably end.
Look at it this way; there are a number of ways you could do this. If we give each letter a single digit (so a = 1, b = 2, …. i = 10 = 1+0 = 1, and k = 11 = 1+1 = 2, and so on), we get a more exclusive list:
1. 666 = sum( dig ( adeline ) ) * 18
2. 666 = sum( dig ( adriel ) ) * 18
3. 666 = sum( dig ( ahmad ) ) * 18
4. 666 = sum( dig ( aisha ) ) * 18
5. 666 = sum( dig ( aydan ) ) * 18
6. 666 = sum( dig ( geoffrey ) ) * 9
7. 666 = sum( dig ( george ) ) * 9
8. 666 = sum( dig ( georgia ) ) * 9
9. 666 = sum( dig ( kyree ) ) * 9
10. 666 = sum( dig ( muhammad ) ) * 18
11. 666 = sum( dig ( myles ) ) * 18
12. 666 = sum( dig ( nadia ) ) * 18
13. 666 = sum( dig ( nathanael ) ) * 18
14. 666 = sum( dig ( noel ) ) * 18
15. 666 = sum( dig ( nya ) ) * 18
16. 666 = sum( dig ( sage ) ) * 18
17. 666 = sum( dig ( sage ) ) * 18
18. 666 = sum( dig ( samara ) ) * 18
19. 666 = sum( dig ( samuel ) ) * 18
20. 666 = sum( dig ( savannah ) ) * 18
21. 666 = sum( dig ( scarlett ) ) * 18
22. 666 = sum( dig ( susan ) ) * 18
23. 666 = sum( dig ( tatiana ) ) * 18
24. 666 = sum( dig ( wayne ) ) * 18
That’s 24 out of 2000 (1.2%). No name of Jesus here.
Doh! You’re going to notice Muhammad is in both lists, aren’t you

?
Oh yeah, you might want to reduce the percentage even more than that, because half the names aren't even using 9 as the (prime) multiplier. Of course is that to suggest these are the only names which can be factored into the number 666? Now that is impressive! Or, am I mistaken here? ...
Can you see though why some here would be worried that, for example, if it
added to the meaning you found in these numbers, you would instead say that 18 is equivalent to 9 as 1 + 8 = 9, and want to use the entire list?
