Cecil Family History
Cecil Surname Meaning
Welsh (Monmouthshire): from the Old Welsh personal name Seisyllt sometimes wrongly said to derive from the Latin name Caecilius (see Sisley).
The most frequent modern spelling is a Renaissance attempt to connect the surname with Caecilius in the English pronunciation of its time.
The Welsh name is more probably but not definitely from the Latin name Sextilius, a derivative of sextus ‘sixth’.
