There was a group of Cayleys living in the Weald area of Sussex and West Kent in the 17th, 18th and 19th centuries. With the help of an Australian Cayley descended from them, I have been able to establish most family linkages back to the late 18th century but not beyond. In medieval times, the Cayleys from whom the Yorkshire Cayley baronets descended had lands in Sussex, and I have long suspected that these later Cayleys were from the same family.
One of my new year resolutions is to see how far back I can take the ancestral lines of Sussex Cayleys. I have now started systematically pulling together raw data from parish registers and other sources available online. Wish me luck – and if you feel like doing some online research yourself, and sharing the results with me, please do!
A longer term ambition is to do the same for Caley/Cayley families of East Anglia. It is proven that not all the medieval Cayleys moved from East Anglia to Yorkshire, and some held influential positions in East Anglia in late medieval times, though exact family relationships are not clear. Again I suspect that at least some more recent Caleys/Cayleys were descended from medieval ancestors of the Yorkshire baronets. As someone who indulged in chocolates produced by the Caley firm of Norwich when a child, I would love to establish the link!
