"Blend of Kay and ton"
The name Kayton is commonly a unisex name from the "English" origin.
Kayton is a modern American formation built from the given name Kay plus the -ton ending found in English surname names such as Clayton and Payton. It first appears in United States birth records in 1992, and no earlier recorded use is known. The same letters could also be read as a respelling of the surname name Keaton, which is pronounced differently, and the record does not settle which reading is correct.
The pronunciation of Kayton is KAY-tun.
