I have a little information on a William Averre or Avery, i.e. from the 1871 census for Platt, Wrotham, Kent.
William Averre, aged 8, was a pupil at the school where my g.grandfather, Edward May, was headmaster.
The place of birth for William Avery was Barking, London.
The name of the school was the Commercial Boarding and Day School, St Mary's, Platt,Borough Green, Wrotham, Kent. (The school was also known as the Commercial Academy)
If a copy of this census or more information about the school is required, please e-mail me at janiejoy@onetel.net.uk
