Con, a fiddler, was born and reared in Cruachlann,
Teileann,
where he was exposed to musical influences such as his cousins; John,
Paddy and Frank
Cassidy. Other players who were prominent at the time
included Mick McShane, Jimmy
Lyons and Connie Haughey. Apart from
periods in the 1940's and 1950's spent working in England
and a short time in Belfast, Con lived the rest of his life in Teileann.
In 1948 he married Mary Kate McBrearty, also from Teileann and
they settled initially at An Cheapach and later in the townland
of Iomaire Mhuireanáin where they reared three daughters.
His modest character and devilish wit made him a very popular figure
in traditional music in south-west Donegal up until his death in 1994.
Although a very individual fiddle player with a unique style, Con formed
strong playing partnerships with among others, James
Byrne, Dermot McLaughlin and Dermot
Byrne. Con's playing can be heard on the CDs 'The
Brass Fiddle' (1987) and 'Con
Cassidy - Traditional Fiddle Music from Donegal.' (2007)
