This comes from the Ireland, Petty Session Court Registers, 1818-1919 for Mathew Sweeney
Kerry,Tralee, 1859-1860.
Now that I know Def is defendant and Comp is complainant and the meaning of Inst, it's easier to understand what's happened. The long and short of the story is my 3 x GGF Matthew and "his arch ememy" Henry Shea had regular dust ups as there are many records when they make complaints against each other in court.

I strongly suspect they were related, I have strong DNA matches to the Shea's in Tralee but haven't made the connection yet.
