Aghadowey, I am descended from a Tristram Moore tried at Newtown Limavady as an Irish rebel and transported to Australia in 1802. He was possibly on the Postlethwaite in Belfast Harbour in late 1790s and a Captain in the rebel army.
There are Tristram Moores in Tamlaght Finlagan in the 1800s and a few in USA records fdrom 1764.
As Tristram wasn't a common name I have been looking for connections between the various to throw light on mine.
On the weekend I googled and came across this:
William Moore, born in Ireland about 1680, though not of the original 16, is supposed to have been one of the early settlers of Londonderry (New Hampshire). He was the father of William Moore of the Cape Ann Association, who settled in New Boston, NH, about 1756, and came from that place to St. David (in New Brunswick, Canada) with his large family, probably in 1785. He built the first mill at Moore's Mills, where his son Tristram Moore succeeded him in the business. His wife Hannah Livingstone was a remarkable woman, of whom there are many quaint and curious tales.
The Tristram mentioned in above paragraph had a son Horatio Nelson Moore who had a son about 1850 called Tristram Moore.
The above clarifies for me the origin of the Wm Moore who went to Moores Mills in 1785 and his father was from a valley near Coleraine, so not far from Tamlaght Finlagan and Aghadowey. Apparently they came from Scotland about 100 years before the 1718 Migration but the above Moores to the USA after 1718 and not among people of 1718.
I suspect they had a common ancestor called Tristram Moore and the name went down the generations through brothers and uncles. Does there happen to be a Tristram in Bolton's Scotch Irish Pioneers?
The search continues.
