Hello,
I would like a few census lookups please. 
He might be found in Cambridgeshire or Suffolk.

William Cann, b. 1843 Cambridge  (Hawker in 1881)

for 1871, wife and first son should be there:
Emma, b. 1845 Bishop Stortford, Hertford
George, b. 1870 Cambridge

They are in Haverhill, Suffolk at the Weavers Arms Inn in 1881.

Thanks very much for any help,
Charlotte
