Cecil Family History
Cecil Name 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’.
