SCALLAN Family History
Recorded as Scallan, Scallon, sometimes Scullin, and originally O' Scallan, this is an ancient Irish surname. It originates from the pre 10th century O' Sceallain, which itself derives from the word 'sceall' meaning the stone of a fruit or the kernel. Many, indeed the majority, of Irish clan surnames originate from what was usually a descriptive nickname for the originator or first chief of the clan, perhaps a thousand or more years ago. Presumably this chief was a tough nut, as it is not very different in origin from the Danish personal name 'Cnut' of which its most famous holder was the legendary King Canute of Denmark and England.
