Dalen Quaice

Commander Dalen Quaice was a Starfleet officer during the 24th century. He had a wife named Patricia.

He was a native of Kenda II who would mentor Beverly Crusher when she had her internship on Delos IV and the two would become good friends. His wife would die in 2367 and Dalen would be depressed that he would say bye to more lifelong friends. He would board the USS Enterprise (NCC-1701-D) to be shuttled home when Crusher was caught in a warp bubble experiment of her son's, where everyone disappeared. Quaice would be the first to disappear. 

Alternate Timeline
In an alternate timeline, where Ira Graves had created the technology to transfer sentient minds into android bodies, Quaice had his mind transfered into one such body that appeared to be very young. He would then serve as chief medical officer of the Enterprise-D after Beverly Crusher transfered off.
