Sorry,
I didn't word that very well, I did mean his name was not put on when the headstone was put up for Anne, I have several cases of people known to be buried in a plot but no name on the head stone which was put up later when another family member died, but that was in an rural area where the same plot stays with one family for generations, city burials are often quite different, so of course he could be somewhere else.
It didn't help that I thought I was only searching Mount Jerome and didn't notice the result was for Deansgrange.
