The Cayley crest
There are a number of Canadian Cayley families of Irish origin. The original irish surnames were probably Keeley, Kelly or something similar, and the spelling of the surname may have been changed because there were prominent Cayleys in Canada.
One of these families was that of Lawrence Cayley, born in about 1832 in Ireland. He came to Canada in 1871, and worked as a painter/decorator, living in Oshawa, Ontario. He died before 1901.
