1861 census:
RG9/409 110/36 (continuing onto 111/37)
22 Melbourne Place, Plumstead
Moses Harvey, 32 ,grainer and printer, b. Somerset Bath
Joana, 25, wife, b. Ireland
Henry, 3, son, b. Hampshire Portsmouth
William, 9, son, b. Greenwich
freebmd shows two possible marriages, 1849 and 1860, for Moses in Lewisham, and a birth for William Henry in Greenwich in 1852 (suggesting he made himself a little older in the 1871 census, maybe because his wife was slightly older than him). I'm not sure Moses's first wife (William's mother) was.
