I am descended from the Cossey family of Earsham and Syleham. Villages in the Waveney Valley Suffolk. The family were descended from the De Contessy family that came to England at the time of the Norman conquest.Their occupations were mainly agricultural but later during a recession some branched out into other trades. Some settled in London to make their livings others remained in the Waveney valley I have yet to discover if any emigrated overseas.
