Of Australian origin, said to represent an Aboriginal term for the boomerang. However, it seems more likely that the name is an invention, influenced by Kyle and Kelly. It has been very popular in Australia and, in part due to the Australian singer Kylie Minogue (b. 1968), has also acquired currency in Britain and elsewhere in the English-speaking world.
English: probably a variant of Skegg, which Reaney and Wilson describe as a nickname from Old Norse skegg ‘beard’; curiously, though, the modern surname occurs chiefly in Hertfordshire, with very little evidence of it in the north, where it might be expected to be concentrated.
