Samantha Jones
From FEInfobase
Samantha Jones, a bubbly vivatious blonde was assigned to Fleet Admiral Picard as his aide. The pair had been working together for over 4 years at the time of Picard's death.
She only ever referred to Picard as Admiral or Fleet Admiral Picard, unless she was flustered in which case she occasionally called him by his full name Jean-Luc Picard.
