"Upset" & other nomenological phenomena

[sagehen]

My father was born & christened  Sherlock  (after his grandfather,
S.A.Bronson) in 1878, some years before Conan Doyle created his character.
Sherlock Holmes's iconic stature has since rendered "Sherlock" virtually
out-of-bounds  as a given name. I've never encountered another Sherlock.
I suppose there are other examples of this sort of thing, but I can't think
of any, offhand, in the English-speaking world.
