For what it's worth, in the STO mission Badlands
, Thomas Riker is mentioned: After the Dominion War, the Cardassians abandoned the work camp/prison planet Lazon II. Thomas formed a community out of the ex-Maquis, criminals, etc. He died of a broken heart when his wife, the colony's botanist and farming expert, died in an accident.
The story was related by his son, Joshua Riker.
When Starfleet learned of the colony in 2409, they sent a ship with medical supplies to fold the world into the Federation.
