"Lady Gethin" is an Irish planxty in C Major. This tune was probably composed by blind Irish harper Turlough O'Carolan (1670-1738) and although Donal O'Sullivan (1958) in his definitive work could find no incontrovertible evidence for its origin, he believes it can be stylistically attributed to him. The subject, suggests O'Sullivan, was Margaret Eames, the wife of Sir Richard Gethin, 3rd Baronet, whom she married around 1725. She was the daughter of Colonel Eames. At the time of her marriage Sir Richard was the High Sheriff of County Sligo. She survived her husband by a few years and died before 1778. The earliest source this tune is the P.W. Joyce manuscripts (Dublin). Joyce noted the tunes in 1912, "copied from a small MS book lent me by Mr. Patrick McGrath...Dublin. Many of the airs were very incorrectly written and required careful restoration. The names are generally in both English and in (correct) Irish." O'Sullivan says the titles suggest they were noted in Connacht, probably County Mayo. It was printed in Complete Collection of Carolan's Irish Tunes (1984), O'Sullivan's Carolan: The Life, Times, and Music of an Irish Harper (1958) and Ossian's The Complete Works of O'Carolan (1989). It was recorded by Derek Bell on Carolan's Receipt (1987).
