Robert Stayner Holford (1808–1892), of Westonbirt, in the village of Weston Birt,[1] Gloucestershire, MP for East Gloucestershire, was a wealthy landowner, gardening and landscaping enthusiast, and an art collector. With his vast wealth, he rebuilt Westonbirt House from the Georgian mansion erected only decades earlier by his father, and founded the Westonbirt Arboretum after succeeding his uncle and father between 1838 and 1839. His London home was Dorchester House.
Holford served as MP for East Gloucestershire from 1854 when he was elected in a by-election on 19 December on the death of the member Sir Michael Hicks Beach, 8th Baronet (d. 22 November 1854), and continued in that office for eighteen years. He was re-elected in 1857 with Sir Christopher William Codrington and again in 1859 with Codrington (who died 1864 forcing another by-election). He was re-elected in 1864 with the new member Sir Michael Hicks-Beach, 9th Bt. (son of the previous MP). In 1872, he vacated the seat.
