William Connellan (c.1630; date of death unknown)[1] was an Irish harper and composer for the harp.
William is famous for the words and music of "Molly McAlpine", sometimes also known as "Carolan's Dream".
Turlough Carolan, Ireland's pre-eminent harper-composer of the late 17th and early 18th century, loved the song so much that he is stated as having said that he "would rather have been the composer of 'Molly McAlpine' than of any melody he himself had ever composed".
[2] He may also have composed the tune "Caoineach Luimnigh" (The Lament for Limerick).
