Guillaume de Layc
Guillaume de Layc, Bailiff of Jersey 1405-06
This Bailiff's name is shown as de Laye by most sources, but an article in the 1970 Annual Bulletin of La Société Jersiaise by Joan Stevens and Jean Arthur concerning papers relating to the du Costil (du Cotil) family held in the La Haule Manor collection, gives the spelling as de Layc (de Laic). It is not a name commonly encountered in Jersey, but this spelling seems far more likely.
The article refers to Guillaume de Layc's seal, with a motif which appears to be a dog, or similar animal, with a bushy tail, and a surrounding legend which confirms that he was followed in office by Thomas Danyel, who held the position for 19 years.
