"Castle Kelly", in Gaelic "Caisleán Ui Cheallaigh" or "Cumar na Cathrach" also known as "Castle Kelly’s", "Castlekelly", "Jimmy’s Folly" and "Kelly’s Castle" is an Irish reel in A Minor (Carlin, Heymann, Johnson) or A Dorian (Breathnach, Flaherty, Harker/Rafferty, Joyce, Mulvihill, Treoir). The parts are played AB (Flaherty), ABB (Breathach, Johnson), AAB (Joyce), AABB (Heymann, Miller, Treoir), AABB' (Mulvihill) or AA'BB' (Harker/Rafferty). There are numerous Castle Kelly's to which this title may refer including Aghrane, now Castle Kelly, in the county of Galway (where O'Carolan composed his air "Mabel Kelly"). In fact, at one point in their history the O'Kelly's had as many as eighty castles in their territory. The tune was entered as an untitled reel into Book 2 of the large c. 1883 music manuscript collection of County Leitrim fiddler and piper Stephen Grier (c. 1824-1894). The earliest recording of the tune was by the Lough Gill Quartet in 1941. It was printed in Breathnach's CRÉ 1 (1963), Carlin's Master Collection (1984), Flaherty's Trip to Sligo (1990), Harker's 300 Tunes from Mike Rafferty (2005), Heymann's Off the Record (1990), Johnson's Kitchen Musician No. 5: Mostly Irish Airs (1985, 2000), Joyce's Old Irish Folk Music and Songs (1909), Miller's Fiddler's Throne (2004), Mulvihill's 1st Collection (1986) (appears as "Kelly's Castle"), Peoples' Fifty Irish Fiddle Tunes (1986), Prior's Fionn Seisiún Book 2, Roche's Collection of Traditional Irish Music, vol. 3 (1927) (as "Cumar na Cathrach") and Treoir, vol. 37, No. 3 (2005).
