Here are a few I'm aware of whose origins I think are generally accepted, but I'm sure there are more:
Grimlock
(by Albie Fiore)
Inspired by the morlocks in H.G. Wells' The Time Machine (1895), particularly their portrayal in the 1960 film by George Pal.
Meenlock
(by Peter Korabik)
While the name likely has its origins in Wells' morlocks again, their portrayal adapts the demonic entities from the 1973 TV movie Don't Be Afraid of the Dark written by Nigel McKeand and remade in 2011 by Guillermo del Toro.

(by Andrew Torchia)
Their name was possibly coined by blending Sasquatch and Sagoth, a race of ape-like humanoids (serving the "orc" role) appearing in Edgar Rice Burroughs' Pellucidar series, first appearing in At The Earth's Core (1914).
