There is a Ballaquayle Road and Ballaquayle School in Douglas. Lots of manx places commence "Balla.." It is Manx for "farm of" (I believe - I am not a Manx scholar!) Usually Balla is followed by a Manx surname, and Quayle is one of those. Other Balla names are Ballakermeen, Ballakaighen, Ballafletcher etc. Presumably, before Douglas expanded to its present size, the area around Ballaquayle School would all have been farmland belonging to a Quayle family.
