3753 Cruithne           Discovered 1986 Oct. 10 by J. D. Waldron at Siding Spring.
Named for the most common term used by the Irish for the Picts---one of the ancient peoples of Scotland. `Cruithne' was the eponymous ancestor of the Picts, and it was his seven sons who gave their names to the seven divisions of the Pictish Kingdom.
