Why is Alfred Josephs, not down on the 1881/1891 census ?,could it be because he is known by another name
Suzard found a possibility for him on 1891 census - you could try each of the male names and cross reference them on the census
I've been trying to see if I can match up the names from the censuses with birth entries on FreeBMD only found these so far
