All of my ancestors from Ireland came to Australia from the northern part of Ireland, before it was known as Northern Ireland.
The Carricks and Matchetts came from County Armagh and the McBarrons and Bells came from County Fermanagh.
These people all appear to have been farmers or farm labourers. Thomas Carrick's father, also Thomas Carrick, was noted as the tenant farmer of one acre of land belonging to the Wakefields, a local Quaker family. Just how a man could support a family on one acre of land as well as paying rent for it beats me. It now appears that there were many members of this Carrick family in the Tartaraghan area and I am working with my assumed cousins who still live in the same area, to pinpoint the connections.
I have not yet found a great deal on my McBarron ancestors except that it appears that after the head of the family, Hugh McBarron, died in 1847 (the famine?), the rest the the family decided to emigrate to Australia. The evidence is that they came from the Irvinestown area in Derryvullen Parish.
