Join the Cayley surname project! I have just started a one-name study for the surname Cayley - variant Cailly. I would welcome all contributions. I have extensive information on Cayleys associated with the Cayley baronets of Yorkshire, which I will add to Wikitree. I also have information on a number of other Cayley families: some of these - particularly Cayleys stemming from East Anglia and Sussex/Kent - may well be descended from ancestors of the Cayley baronets, but I have never been able to establish this. Help is also needed to establish likely links between some of these other Cayley lines.
