Seven of Nine reads Craig's name in a list of deceased crewmembers
Claudia J. Craig was a Starfleet officer assigned to the starship Voyager, an ensign who was killed in the line of duty sometime before 2377. Craig's name was read out on a casualty list of all who died during that vessel's journey through the Delta Quadrant. (VOY: "Imperfection")
Background
This name was devised for the list, it was not mentioned as a casualty in any other episode. It is possible this name refers to one of the officers killed en route when Voyager was dragged to the Delta Quadrant.
As with many names on the "Imperfection" list, C.J. Craig is an in-joke (albeit mispelled) referring to the character on The West Wing.
