More info given in another thread Here:

(Murpholly)I concede that Lass of Richmond Hill is not a folk song by some definitions being written by Leonard McNally and music by James Hook and first noted in 1789. (Old enough to be a folk song? It has a roud number). McNally married Frances L'Anson in 1787. Her family had a great deal of property in Richmond, Yorkshire including "Hill House" so think Steve that as a Yorkshire man you might accept the Richmond is that in the North Riding and as a Yorkshire Briganti I claim it for Yorkshire despite those southerners. Just a pity that McNally betrayed his United Irishment comrades later on.
