Tadgh Ó Buachalla (anglicized as Timothy Buckley) aka Tadhgín an Asail (little Tadgh of the donkey) aka Tadeen the Fiddler aka Tadeen the Cobbler was a travelling music master from Park, Knocknagree active in the latter half of the 19th century. He also lived at various times in Kiskeam and Scartaglin. It’s likely he got his music from Corney Drew, and he passed that tradition to his pupils, including Din Tarrant and Tom Billy Murphy. He made his living travelling the countryside on the back of a donkey (a noteworthy mode of transport even at that time) and mending shoes when he wasn’t teaching music. His pupil Tom Billy would later adapt the ABC notation he used (as well as the knack for donkey-riding) when he became a renowned teacher himself.
At least one slide is still commonly called Tadhgín an Asail’s, and the polka known as The Cobbler may refer to him as well.
