This is an English form of a Germanic personal name composed of the
elements "Frid" or "Fred" for peace and "Ric" meaning power,
introduced into England by the Normans. This was a hereditary name
among the Hohenstaufen ruling Family, hence its popularity in
Central Europe. Within England, the name appears chiefly in the
Eastern Counties, the Duke of York and Albany was Augustus
Frederick (1763 - 1827) married the eldest daughter of Frederick
William II of Prussia in 1791 and was made quardian of the King in
1818. Going back in time, records show that a James Fratherick
married Katherine Simonds on 29th September at St. Dunstan's in the
East London, and the infant Anne Frederick was christened on the
20th October at St. Mary's White Chapel, Stepney. The first
recorded spelling of the family name is shown to be that of
Walter Frethryk, which was dated
1275, The Hundred Rolls of Suffolk, during the reign of
King Edward I, The Hammer of the Scots, 1272 - 1307.
