According to the chart "Medical Log SD 47215.7", Ensign G. Jetson was a Starfleet officer in the 24th century. They were listed with other individuals in a USS Enterprise-D medical log.
Based on the stardate, this chart was possibly made for the Star Trek: The Next Generation seventh season episode "Interface" which began on stardate 47215.5. The chart was put up for auction in 2018. [1]
The chart was heavily populated with jokes, making it likely that G. Jetson was a reference to George Jetson.
