Hi,
Wouldn't you start looking for the birth registration of Joseph from the Dublin GRO or at your local family history centre? Do you have his death cert from the same place? Same for Marriane's as this would give you her mother's maiden name.
If Henry was from Yorkshire, look for his in freebmd.
They should all in the 1901 and 1911 census, worth checking for the pub and at any address from certificates.
Hope this helps
Kate (the one with the ideas, not the directories!)
