Hi Cliff
There were a lot of Harry DAVEYs born in England about the same time as your father. I did see this one in Maidstone but whether it is of any relevance I don't know

1881
33 High St, Maidstone
James DAVEY head mar 40 tobacconist b.Camberwell
Louisa wife 35 b.Maidstone
Blanche dau 11 b.Maidstone
James son 8 b.Maidstone
Sylph dau 7 b.Maidstone
Harry son 5 b.Maidstone
Violet dau 4 b.Maidstone
Susan FRY servant unm 16 general servant b.
RG11/927 folio 60 page 17
If you think it may possibly be the correct family then some of the other census years can be posted as they appear to have remained at the same address for some years.
If you are unsure, it may be worthwhile searching for an obituary for your father to see if there is one and whether any family names are mentioned
