The surname Ozanne is one of the oldest Guernsey surnames. There are many theories about the origin of the name. Some claim it came from the name of the heralds, "The Hosannas", who brought the Holy Grail to Glastonbury. Others claim the name comes from the name of a river in Turkey.
The earliest reference to the surname Ozanne in Guernsey is in the Rolls of Assizes of 1309 when Richard Ozanne "encroached on the king's highway".
According to an old Ozanne Pedigree "the family of Ozanne is one of the most ancient and respectable of Guernsey, and the name can be traced to the reign of King Edward III (1327-1376), at which period 'Sire Denys Ozanne, Pretre' occurs."
The earliest ancestor I have been able to trace is Jammes Ozanne of the Castel parish who married Marie le Maistre, and started a long line of James / Jacques :-
