In the notes, the tune is attributed to William Marshall of Fochabers, Morayshire.
American and Irish relatives found here…
Most of the links here are to completely different tunes. This tune is in fact a reel, not a hornpipe, and is simply called The Marquis Of Huntly’s Reel (one of two or three tunes of that title). It was supposedly written by Peter Milne, a famous fiddler from Tarland in Aberdeenshire, and first appeared in his collection of 1870.
There is another, different tune, which has the same name which is attributed to William Marshall
Thank you "niall_kenny", for those quite important informations. The type of dance is changed, now… Since Sean Keane’s version probably is an arranged one, feel free to post the original abc in the comments (if you have it).
Sean Keane wouldn’t be the best musician to learn Scottish music from. I think Paul Anderson - also a fiddler from Tarland - recently released a book of Peter Milne’s tunes, in fact just a couple of weeks ago. Should be available, possibly from the Elphinstone Institute of Aberdeen University.
