Reg Cundick and Danny Howell in the book The Inns And Taverns Of Warminster, published in November 1987, stated:
The Swan Inn is recorded in the 1801 Survey Of Warminster at Plot No.427 on the north side of the Market Place.
It was once in the hands of the Pool family. When William Pool died, aged 37, in 1802, his wife continued the business for many years afterwards.
Page 47 of Rambles In And Around Warminster (written in 1883) notes Mrs Pool’s reputation as a remarkably careful business woman. Apparently, a sixpence belonging to her had broken in two, so she sent it to a brazier to be mended. He accomplished the work so neatly that the sixpence was spent without difficulty, but the satisfaction of his customer was very much lessened when she received his bill for seven pence for mending the coin!
Mrs Pool was still at the Swan Inn in 1822-1823 but had left by 1830, when the occupier was John Gingell. Mrs Pool, who moved to North Row, Warminster, died in 1844, aged 81.
By the time the 1838 Survey Of Warminster was compiled, the inn had closed, having changed into a private house. Joseph Vidler Toone, who came to Warminster from Salisbury, about 1853, converted the house into a chemist’s shop. Toone was in business here until about 1880 when he sold out to Charles James Rawlings, a chemist from Frome. Toone moved to Bath, where he ran a chemist’s shop at New Bond Street, but returned to his former Market Place shop in Warminster before the end of the 19th century. Toone retired to Bath about 1901; the Market Place premises were then used as a tearoom and restaurant by Mrs Frances Down. From the mid-1920s to the late 1930s Mrs Amy Butler ran a millinery business at the building, which later returned to life as a chemist’s shop when Boots opened their Warminster store. They still trade from the same building, west of the Bath Arms, today, but have extensively modernised the property.
