I have found a William Vevers at the Classical and Commercial Academy, 36 Mason St, Hull in 1851. The reference comes from a trades directory. Does anybody have access to the 51 census, or know about this Academy? My ggggf William Vevers lived in Hull in the 1840's and moved to York by 1848, but I wonder if it's possible that the trades directory may be referring to a business address. William had a bookshop in York, and earlier was a travelling periodical bookseller, so I'm thinking that maybe there was more than one branch, and this academy may have been in fact a book shop. My William was definitely at home in York in the 1851 census, but his son John wasn't. Andrew Vevers
