Although la chasse is French for 'the hunt', in the context of house names the word is not connected with hunting, but means that the house is approached along a drive or avenue. In the case of Les Chasses, itusually means that there are two such approaches.
Joan Stevens' Old Jersey Houses notes that it is not the St John house, in Rue des Chasses, itself, probably dating from about 1750, but a far older building at right angles to it, which could date from as early as 1520.
The book gives no information about any of the house's owners, but the second volume suggests that it may be as early as 1717 and that documents found in an attic suggest that it was then in the possession of Jean Le Boutillier. He may have been the Jean who married Sarah Dorey in 1713. A plaque on the west wing of the house is inscribed SLF.SHB.1715, but this gives no clue to occupants of the property, because it is believed to have been brought from a St Helier property.
