The title "Rudha Dubh" means something like *Dark Headland* or *Black Point* (from gaelic *Rudha* and also "Rubha": headland, promontory, point [of land] and *dubh* meaning dark or black - rf. Carmichael et al., 2014, *Gaelic Place Names of Arrochar Parish*).

It remains unclear which "Rudha Dubh" is referred to, because the dance description does not specify a specific one.

There are several places named Rudha Dubh throughout Scotland like on the coast of the Isle of Islay near Lower Killeyan, a small promontory on the north-west corner of Isle of Bute, another on the East cost of the Isle of Tiree, one with a lighthouse built on near Scalasaig on the Isle of Colonsay, or the Black Point jutting into Loch Grunabhat. 

A famous one involves the SS Politician which ran aground the cliffs of Rudha Dubh at island of South Uist in the Sound of Eriskay in 1941 with a cargo including 28000 cases of malt whisky. This event gave the inspiration for the novel "Whisky Galore" and the movie "Whisky Galore!".
