Celtic mythology
In the Celtic language, the Daoi-Sith are "dark elves", while the Du-Sith are "black elves". Both terms are obscure, and the latter seems to have been used as a proper name. There are no known surviving myths or stories associated with these creatures in Celtic mythology, so it is impossible to tell whether they were thought to be elf-like, troll-like, or something completely different, or if they were even similar to each other, if they were good, evil, or either, etc.
While the terms exist and were apparently used for something, it is currently impossible to tell exactly what. However, it seems very likely that they are related to the Trowe and Drow of Scottish folklore, if not direct precursors.
British Isles folklore
In the Orkney Islands, the Trow or the black elves are similar to the Svartalfar or to Scandinavian trolls or dwarves, and inhabit mines and caves. They may be either good or evil, but the evil variety are more common.
The Drow or the dark elves are the Shetland Isle equivalent of the Trow, but unlike the trow, they are thought of as exclusively evil. They are tiny elves known for their mining and metal-working, not unlike dwarves. A useful way to envision them may be as evil, subterranean counterparts to tiny shoemaker elves.
