There in a note in Dublin Poor Law Union, Committee meeting 26th Nov 1917 that says:
"A letter was read from the Dublin Metro police which stated that John Dickinson was arrested in England on a warrant, tried before Mr Lawford(?) on the 20th inst. and sentenced to six months imprisonment for wife desertion"
there is no clue as to why they have recorded this bit of info or what the relevance is to them.
