This is a One Name Study to collect together in one place everything about one surname and the variants of that name. The hope is that other researchers like you will join our study to help make it a valuable reference point for people studying lines that cross or intersect. There is extensive information available on families definitely linked to the Cayley baronets of Yorkshire. It is not clear whether there are other Cayley lines that share common ancestors with the Cayley baronets.

- Unconnected Probable Cailly Family Members: for information from medieval records refering to people with the name Cailly who are almost certainly connected to Cailly family members for whom there are profiles, although it has not been established how they fit in. If any Wikitree members are able to find sources to help make the connections, that would be wonderful!
Origin of the Name
The ancestors of the Cayley baronets came around the time of the Norman conquest from a village near Rouen in Normandy called Cailly. Before the 14th century, common forms of the surname were de Cailly and de Kailly, though there were a number of other variants.
Census and immigration information suggests that some other Cayley lines in England and in other countries varied the spelling of their surname between Cayley and Caley, and that a few families were descended from Irish immigrants originally called Kelly or Cawley.
This study includes the variant surname spelling Cailly, which is the main form of the name found in earlier medieval times.
As with many surnames, in records and sources dating back to the 18th century and earlier the surname is found spelt in many different ways, and some individuals have their last name spelt differently in different records. Among the variants are
The earlier medieval form of the surname, often in the form Cailly, also has many further different spellings in surviving records, including
and even, in one group of records, Kellaway or Kellaways.
The Cayley baronets have been particularly associated with a village called Brompton-by-Sawdon, inland from Scarborough in Yorkshire, England. Today descendants of their family can be found in Australia, Canada, England, New Zealand and the USA.
Other Cayleys can be found in the main English-speaking countries around the world.
