Thomas Hampton was born at Blaisdon in Gloucestershire (baptised March 1844), and probably worked on the canals for a while. By 1870 he was living in Hereford, being married there that year. He died in 1896, still resident at Bath St. Hereford. He left a manuscript containing tunes, which is now in the possession of his great-great granddaughter, Becky Dellow, who is researching both TH and the tunes. Although the manuscript was compiled in Hereford, Becky believes some of the tunes were remembered from TH’s childhood in Gloucestershire.

The Last Rose of Summer was published in Moore’s Irish Melodies, published between 1808 and 1834. Moore allegedly took the melody from Alfred Milliken’s 18th century song, The Groves of Blarney, which in turn is reputed to have borrowed the tune from a 17th century harp melody.
