The names are in English on JASRAC so they look fine:

Full name for the first one should be Howard Ellington Riddiford Barnes. No idea about the other one.
I think Rock is fine for the title. Also added the English title to this one and a few others that were missing it so at least they're somewhat consistent (the title was on some reprints).
EDIT: I wouldn't write it in all caps, it's a normal name. JASRAC always write English in all caps for some reason, but we don't follow that.
