Patrick Duigenan

Patrick Duigenan, PC (I) KC, FTCD (1735–11 April 1816), Irish lawyer and politician, was the son of a Leitrim Catholic farmer surnamed Ó Duibhgeannáin.

Through the tuition of the local Protestant clergyman, who was interested in the boy, he got a scholarship in 1756 at Trinity College, Dublin, and subsequently became a fellow. At some point he joined the Anglican faith. He studied law at the Middle Temple, was called to the Irish bar in 1767 and was appointed Grand Secretary of the Orange Order in 1801.
