I am fascinated by this idea, and I found two interesting data points:
h t t p s://zarthani.net/traveller/history.htm refers to Darrian outposts all through what would later become the Sword Worlds, and Bowman is listed, citing Alien Module 8 and a number of GURPS Traveller references on the Sword Worlds.
AM8 blurb: "There was an extensive presence in District 268. A research facility on Dawnworld continued to operate for several years until its operators finally died of old age. A Darrian mining colony in the Bowman Belt suffocated when resupply ships never arrived. Small outposts throughout the subsector died off when their expected relief ships failed to show up."
This game log indicated the archeological investigation of the old colony was on Bowman/Epsilon:

For whatever reason, the forum thinks I am a spammer for including these references, so I added this text at the end to not appear spamlike.
