What I think I saw, on the admission details of her g.grandfather to the asylum, was that his religion was given as Roman Catholic, so maybe he did take his wife's religion after all. I also wondered do Irish death certificates not show the cause of death? If so, Dervla would have known what he died of.
However, that recorder should have been struck off, although I guess at 73 he'd already caused unnecessary hardship to a great number of people.
Just shows how stiff sentences were in those days, even allowing for the fact that he was obviously given a longer sentence because of his race, but 12 months for throwing a brick at a window and breaking nick-nacks inside the window is astounding. Oddly, from the name Mrs Marks, it seems the window owner was also Jewish.
