Susannah West Holford, Lady Holford was an English socialite. She was the daughter of Arthur and Mary Wilson of Tranby Croft, Yorkshire. Her second husband was Sir George Holford who owned Dorchester House in London, Westonbirt House in Gloucestershire, and Westonbirt Arboretum which is still enjoyed by the public today.

Westonbirt House is a country house in Gloucestershire, England, about 3 miles (5 km) southwest of the town of Tetbury. It belonged to the Holford family from 1665 until 1926. The first house on the site was an Elizabethan manor house. The Holfords replaced it first with a Georgian house, and then Robert Stayner Holford, who inherited Westonbirt in 1839, replaced that house between 1863 and 1870 with the present mansion which was designed by Lewis Vulliamy. He also remodelled the gardens, diverted the main road and relocated the villagers.
