Gawne is the Celtic Smith !- the name has been found on Mann since the earliest records.

A W Moore writes:
GAWN and GAWNE, contracted from Mac-an-Gabhain, ' the smith's son.'

The smith, in olden times, was a very important personage, as being the maker of armour and weapons, and as this trade, like others, in that day descended from father to son its designation would soon become used as a surname.

MacFlrbis states in his book of Genealogies that the MAC-AN-GHOBHAN were historians to the O'Kennedys of Ormond.

'Maelbrighde MAC-AN-GHOBIIANN,' A. D. 1061.*

Henry GAWEN was "Atturney" in 1517.
