Thanks for sharing this info on John McPartlin and Margaret Burns ....and their offspring!!.
It would appear that they are the parents of Peter C McPartlin born in Sligo in 1876 (my Great Grandfather). Peter's family home on Dorset Street in Dublin is still in the name of McPartlin, but it is currently rented out to employees working in the Mater Hospital in Dublin.
Peter was an active volunteer in the Easter Rising of 1916, stationed in the GPO on O'Connell Street.
His name is listed on the Roll of Honour website... http://1916rebellionmuseum.com/1916-easter-rising/roll-of-ho...
Peter had a son also called Peter (my Grandfather) who was unfortunately a victim a serious mugging and death by drowning in the River Liffey (beside The Halfpenny Bridge) in 1952.
I would be delighted to hear of any further information on John McPartlins parents. From reading this thread it maybe the case that John's father arrived in Sligo from Scotland which would be great to confirm.
