Another possibility could be “Stan” or “Stanislaw” (because of Stanisław Lem).

Lemmy of Motörhead’s real name is “Ian Fraser Kilmister,” so our guy could also be named “Ian” or “Kilmister;” Fraser probably not being a great choice for obvious reasons.

(Have I spent way too much time thinking about this? Is it way past time for me to stop drinking coffee and go to bed? You bet! ☕🤪)
