Givens

 was a Gunners squad commander. His body is found at the Library in Fallout 4. Judging by the existence of a separate faction, Givens was likely intended to play a bigger role.

Background
"Curator" Givens was the leader of the Gunners' recovery team sent to the Boston Public Library to recover data. Cornered by super mutants, the security perimeter they set up came too late to save the squad and they perished just short of reaching the exit.

Appearances
appears only in Fallout 4.
