You might also be looking for G. Mandel or Starfleet's Ensign Mandel.

In 2293, Geoff Mandel was named as an UESPA representative on the dedication plaque of the USS Enterprise-B. (Star Trek Generations, dedication plaque)

This character was only mentioned in writing.
Mandel was named for production staff associate Geoffrey Mandel. This name was seen on the Enterprise dedication plaque. There was a similarly named person (G. Mandel) on the plaque of Enterprise NX-01, 142 years previous, who could be a relative. There is a slight possibility they are the same person, in the unlikely case that time travel or suspended animation was involved.
