Either you or they are meant to say "for that was not his name" in these cases.
On one project that the Fates may have disliked from the start, I had a need to substitute human names with different human names, consistently. So I made a lookup table, and I made it (1) preservative of binary gender, (2) limited to common names, and (3) changing any name in the first half of the alphabet to the second half, and vice versa. So no one got their own name back.
The Fates, or management, objected that my system could give people with different original names, the same new name. At least I think that's what they didn't like... I don't remember if I tried to argue that some people have the same names anyway, or that confusing the data was the actual point of my activity. At length, the project quietly died; I was doing other things anyway.
