I agree with you there, he did seem to have his fair share of bad luck.
The line that I am searching is Williams son George John, He was born in Dublin in Ireland (again with the forces I beleive) also myself and my aunty are in touch with another of Williams sons' descendants, William jnr. So with help from my aunty the five children were William jnr, George, Charles, Abraham was born in London and Isaac born in Malta. I don't know the dates of these childrens birth though, only George, who was born in 1882.
I msut have been having a dim moment, why didn't I think of the army records for him leaving for Malta. Also on one page of the records it says the name of a street where he was living, in Sliema, I tried googling the street but maybe I didn't get the name right or it doesn't exist anymore.
