Marian McAllum

From Memory Alpha, the free Star Trek reference

Ensign Marian A. McAllum was a Starfleet officer during the Dominion War.

In 2374, a file from the USS Akagi reported McAllum missing in action. A file from the USS Zapata reported her killed. (DS9: "In the Pale Moonlight")

McAllum's name appeared on the casualty list display seen on a computer readout in that episode. It is unclear if the Zapata was her home station.
