My ggg Grandfather Thadeus Duffy b1800 married Catherine Gavin b 1800. They were both resident in Islandeady and got hitched in 1822. So apart from all the fighting some members of our family clearly had eyes for the other.
Many members of the wider family moved to Scotland between 1840 & 1860. They largely settled in the east end of Glasgow in an area name, "The Calton" occupied almost exclusively by the, "Irish".
I was Raised in the, "Calton" and have many memories of the place.
