Souvenir

'Souvenir' was published in Fantastic Universe in October 1954. 
The robot pilot informs Rogers that they have finally reached Williamson's World. Williamson's World was settled by Frank Williamson in the first attempt to establish a Terran colony outside of the solar system. No future evidence of his colony was found and it was presumed lost and it remained so for three hundred years. Rogers meets a young man after landing who assumes immediately he is from the Galactic Relay Center. He identifies himself as Gene Williamson (the great-great-great-great-grandson of Frank Williamson). The two share their admiration for Williamson.
