Jon Monson

From Memory Alpha, the free Star Trek reference.

Lieutenant Commander Jon S. Monson was a Starfleet officer during the Dominion War.

In 2374, as well as later on in 2375, files from starships Akagi and Zapata reported Monson killed in action. (DS9: "In the Pale Moonlight", "What You Leave Behind")

Monson's name appeared on the casualty list display seen on a computer readout in that episode. It is unclear which of the above was his home station, if any.
