At the formation of the free state and yes indeed the border campaign alot of protestants did leave. Im from the scotstown area towards Roslea, and i could point to you 3 orange halls in ruins. If you study the parish History of Scotsown, smithboro, Kilmore and Drumsnatt, you would be amazed to find how many protestant families existed before the formation of the free state, and how many left after it.I know scotstown well (mother hails from there) and I wouldn't agree with the effect of the border campaign at all. Plenty of land in Protestant hands and there still is in at the least the areas between Scotstown and Monaghan town. I'll have to quiz her on the effects of the border campaign as that is news to me.
Drum on other hand - It has "the feel" of a Northern Ireland / English village. Hard to explain but you can almost sense that it is out of place.
Well i know for certain over half my fathers land was previously protestant owned by 4 different families. And my da bought a farm of the neighbour around the 60's that was moving to the north.
Im not saying there was any ill feeling at all, i have no evidence of that, but with close proximity to the border i would deduce alot of protestants felt better moving to the north.
