Charles O'Conor (1764 – 1828) was an Irish priest and historical author.
Reverend Charles O'Conor was educated in Rome and, after a short time as a pastor in Roscommon, left to be chaplain and librarian to the Marchioness of Buckingham. Buckingham invited him to organize and translate a collection of Gaelic manuscripts at Stowe. He would catalogue many manuscripts, including the famous Stou e Missal, now in the Royal Irish Academy. Unfortunately, he suffered from mental illness and returned to die at Belenagare. His brother, Matthew O'Conor, who also planned on being a priest, transferred to law and became a historian.[1]
