Niel Gow
Niel Gow (1727-1807) was born in Inver, Perthshire, and became possibly the most famous Scottish fiddler of the 18th century. He composed a lot of dance music (and was, like many of his contemporaries, not above pinching good tunes by other composers to publish under his own name).
Many of his compositions are still played today at ceilidhs and country dances. He himself spelled his name Niel, although others sometimes spell it Neil or even Neal. (To add to the confusion he had a very musical grandson who did spell his name "Neil".)
Gow's youngest son, Nathaniel, was a composer of note.
