There used to be a handful - Caelum Bliss, Missed In Diary, Black Ocean Drowning...
GLOD was an entity all its own. Would not have called them goth but I sure wouldn't call them industrial, either.
Gargoyle Sox - 80s Detroit deathrock; currently, John Koester has Trapdoor Spiders, which is still kind of gothy but has now been more involved in his dark country outfit Gravetown who sound good.
Not sure if Red Lipstick Death are still around. They're a MI deathrock outfit who have been about these past several years. And born-again Christian DR from what I hear.
We also had Dragon's Tears Descending who had a kind of Death In June sound. And there was Midnight Mourning.
Those are the ones who immediately come to mind.
Oooh! And The Hex! Interesting case there - 3 highschool boys who have never listened to goth or deathrock, set out to form a psychobilly band and serendipitously ended up with a nice dark, deathrockish/post-punk sound. Sadly, they've been broken up for some time now. Still see the guys at shows and mention has been mad of the possibility of re-forming.
