Castel Family Genealogy Forum
I have Castel ancestors in my family and the name, according to Leslie Quilliam in his book Surname of the Manks, is Norse. It's from Asketill = Kettle of the Gods, as = demi-god and ketill = kettle or cauldron.
There are about 20 different ways of spelling the name some of which are: Caistil, Caistile, Castil, Castyl, Kaystyl, Caiskel, Cassall, Caystill.
Do you have connections with the Isle of Man as the name was prevalent in the north of the island but appears to have died out about 100 years ago?
