Are these all the same family? I have found my ancestors' names spelled in all of these different ways, which is confusing my research and the resulting family trees. Many of these profiles need to be merged, since they seem to be all of the same family.
I have found that these names, as well as the names Ciely, Cailly, Cayley, Sele and de Say are all possibly variation on the same name, spelled in different ways. The name seems to have originated in Normandy in the city of Cailly, pronounced "Say-Ye" in French.
