Michael Argyle was one of the first Chief Engineers we see aboard the Enterprise-D in the first season of TNG (2364), and they had several that first year. He has a slight Scottish accent. Having been involved with Kosinski’s warp drive experiment, as well as re-assembling Lore, he has had some interesting stories to tell about his time aboard. At the time, he was at the rank of Lieutenant Commander.
A screen in one of the remastered episodes indicates that he remained aboard the Enterprise-D until 2367. Also, many beta canon sources kill him off one way or another (and either call him Michael or Terence), but you don’t have to stick with that in your quantum continuity. Argyle would be a great candidate for promotion to Commander (or even Captain), and be placed in charge of a space station or re-assigned as Chief Engineer or Commanding Officer aboard another Starfleet vessel. He would also be great as someone in charge of fleetyards or ship design.
