The Island of Jersey is divided into 12 parishes, each of which is subdivided into Vingtaines, with the exception of St. Ouen which is divided into Cuillettes .A Vingtaine meant an area covering 20 households,  and a Cuillette meant a "gathering or collection of people". These are ancient meanings which would have been appropriate when the Island population was relatively small. A map showing the parish boundaries  is shown below.
