Commander Edward M. La Forge: Starfleet Commander in the science division and Doctor of Xenozoology. Married to Captain Silva La Forge and father to Lt. Cmdr. Geordi La Forge. In 2370 learned of his wife’s (and her ship’s) disappearance and talked to Geordi about it. He’d seen Silva not long before her departure.

Captain Silva La Forge: Commanding Officer, U.S.S. Hera. Kept in touch regularly with her son, Geordi. Disappeared in 2370 while on a courier mission from Deep Space Three. After a six-day search her ship and crew were officially declared missing, presumed lost. 

During this time, the Enterprise was on a mission Marijne VII where an alien creature needing help to return to their native space took the form of Captain La Forge to convince Geordi La Forge to help them in that effort. 

Captain Silva La Forge appeared in TNG’s “Interface” and was played by Madge Sinclair who had previously played Captain Margaret Alexander in Star Trek IV.

Vice Admiral Marcus Holt: Base commander, DS3. Reached out to Captain Picard (an old friend) when the starship Hera had disappeared without a trace. The Hera was commanded by Lt. Cmdr. Geordi La Forge’s mother, Captain Silva La Forge, and Picard relayed the information to La Forge personally. Holt directed the search for 6 days until it became apparent that the ship and crew would not be found.

Vice Admiral Chekote: Base C.O. of Starbase 227. In early 2370 he was the Benjamin Sisko’s superior officer. Admiral Chekote was kept apprised of the situation on Bajor regarding the Circle and their demands that the Federation withdraw and the Cardassians’ arming them without them knowing about it. Chekote believed the Prime Directive still applied in this situation, even if they lost Bajor and the wormhole in the process. He ordered Commander Sisko to evacuate the station and worry about the political ramifications later, an order that Sisko interpreted broadly enough to leave a small team behind with him leading it. Sisko’s team along with Major Kira and Li Nalas were instrumental in exposing the Circle’s backing, the Provisional Government prevailed and returned the station to Starfleet.

Weeks later, not long after Captain Picard of the Enterprise was believed killed in an altercation in a bar on Dessica II, Admiral Chekote was convinced by Commander Riker to pursue the investigation of Picard’s death, placing the Enterprise on detached duty.

Admiral Chekote appeared in DS9′s “The Circle” and TNG’s “Gambit Part 1″ and was played by Bruce Gray.

Commander Calvin Hutchinson: Starfleet Officer, usually assigned as an aide or attaché to an Admiral’s Staff or as a Public Relations Officer. He was renowned for his parties and his prolific small talk.

In 2369 he was assigned to Arkaria Base. He hosted a party for the Enterprise senior staff (minus Lt. Worf, who was excused) while the ship underwent a baryon sweep that required the evacuation of the vessel for the duration. However some of the base staff were in league with a team what was siphoning trilithium from the Enterprise during the sweep. When La Forge discovered an odd power signature beneath one of the banquet tables the corrupt staff broke out weapons and shot La Forge and Hutchinson. Hutchinson was killed by the weapons fire, La Forge critically injured.
