One very common practice, when using traditional tunes in hymn compilations was (and probably still is) to use the name of the place the contributor heard or collected the tune as its title. See, for example Monks Gate ...

When Ralph Vaughan Williams was commissioned at the start of the 20th century to edit a new hymnal as an alternative to Hymns Ancient and Modern, he set John Bunyan's hymn, in an adaptation by Percy Dearmer, to his own adaptation of the tune of an English folk song Valiant or Welcome Sailor which he had collected from Mrs Harriet Verrall of Monk's Gate, Sussex.
