"My Lagan Love" is a song to a traditional Irish air collected in 1903 in northern Donegal. The English lyrics have been credited to Joseph Campbell (1879–1944, AKA Seosamh MacCathmhaoil and Joseph McCahill, among others). Campbell was a Belfast man whose grandparents came from the Irish-speaking area of Flurrybridge, South Armagh. He started collecting songs in County Antrim. In 1904 he began a collaboration with composer Herbert Hughes. Together, they collected traditional airs from the remote parts of County Donegal. While on holidays in Donegal, Hughes had learned the air from Proinseas mac Suibhne, who had learned it from his father Seaghan mac Suibhne, who in turn had learned it fifty years previously.
