Hi Sam,
No, unfortunately I don't have a number of a house on Castle Hill and I thank-you for the information on the two Tannery's. I shall follow up on the 1st Rathfriland Presbyterian Church and see if they have any records re him possibly being buried there seeing that that was the church that the daughter called Anne got married in, in 1829
I'm pleased to know that there is a graveyard attached to the church.
Sam, When you Google, 'Castle Hill' do you have any idea what the old, very extensive building is on the right hand side, going up the hill.
Lynn.
