Terence "Cuz" Teahan (1905–1989) was a notable traditional Irish musician and composer from the Sliabh Luachra district.
His mother was a popular singer, while his extended family contained many musicians who played at dances in the neighbourhood.
Among his neighbours were eminent musicians Padraig O'Keeffe, who taught him music at Glountane School, and Johnny O'Leary.
[1] From 1943 to 1964 he played concertina and button accordion three nights a week at the major Irish dance-halls in Chicago, as well as at weddings and cultural events.
He received the nickname "Cuz" because he helped out newly arrived Irishmen by telling them where to find accommodation, work, etc.
