Hello. I have just registered with Wikitree and have started to add a bit of genealogical information. I have an extensive set of information on people with the surname Cayley and maintain a Cayley family history site at https://cayleyfamilyhistory.wordpress.com/ (at this moment, I am about half-way through transferring information from a previous site). I welcome information about Cayleys and do my best to respond to queries relating to Cayley families. I have helped to author a number of pages on Wikipedia about people with the Cayley surname.
