I have an Irish ancestor that came to America. Born 1752 in Ireland. I just don't know where. The thing that I thought was interesting is that he's listed in 2 census for Chippewa Ohio as being one of the men with a gun and ammo to fight Indians in 1816 and 1819. And the libs try telling us that no one owned a gun? THAT Irishman did!
If your ancestor emigrated at that time and especially if he was an Indian fighter in Ohio it is almost certain he was an Ulster Presbyterian from the North and an “Irishman” of a very different stripe from the Catholic emigrants who emigrated from southern and western Ireland since the mid-nineteenth century famine and who settled mainly in the cities of the north and east of the United States.
