I believe you're thinking of Dorn Base on Hoth. Michael Dorn played Worf on ST:TNG.
There's also this Trooper's companion ... Elara Dorne.
And there's an officer called "Doren", I think, both on Dromund Kaas and perhaps on Balmorra as well (but I'm not sure about that anymore).
"Dorn", by the way, means "thorn" in German language.
