"Mrs. Maxwell - first tune", in Gaelic,"Baintighearna Macsbhell", also known as "Madam Maxwell" or "Planxty Madam Maxwell" is an Irish air or planxty in 2/4 time and E Major was composed by the great blind Irish harper Turlough O'Carolan (1670-1738). It is one of two tunes that he composed for Mrs. Maxwell. O'Sullivan writes that Mrs. Maxwell was probably Judith Barry (1699-1771) of Newtown Barry, Co. Wexford, daughter of James Barry. She married John Maxwell of Farnham, Co. Cavan, in 1719, who later became M.P. for Cavan (from 1727-1756), High Sherriff (1739), and, upon succeeding to the estate of Farnham on the death of a cousin, became in 1756 the Baron Farnham of Farnham, Co. Cavan, thus transforming Mrs. Maxwell into Lady Farnham. One of the settings of this tune, for which no words have been found, was recorded by the Belfast Northern Star of July 15, 1792, as having been played in competition by one of ten Irish harp masters at the last great convocation of ancient Irish harpers, the Belfast Harp Festival, held that week. It was printed in Bunting's Ancient Music of Ireland (1840) (as "Madam Maxwell"), Complete Collection of Carolan's Irish Tunes (1984), O'Neill's Music of Ireland: 1850 Melodies (1903), O'Sullivan's Carolan: The Life, Times and Music of an Irish Harper (1958), Samuel, Anne & Peter Thompson's The Hibernian Muse (1787) and Ossian's The Complete Works of O'Carolan (1989). It was recorded by Brian Conway on Consider the Source (2008) (appears as “Madam Maxwell”) and Derek Bell on Carolan's Receipt (1987).
