Looking for Great great grandfather, James Elliott

I have been to Letterkenny since my lastpost was posted. Believe my Elliott's came from Creeve Glebe, just outside Letterkenny. Met a man by the name of Spratt, his mother had been an Elliott, He looked amazingly like my father. The Spratt manmay havecome down from Stephen Elliott and Prudence Elliott (same surname) , married 1862 in District of Milford. I believe Stephen Elliott was from Creeve Glebe. I'm looking for my great great grandparents, James Elliott and Ann Clark. Married 4 Jan 1825 at Letterkenny Church of Ireland by Rev. Joseph Stopford. He is buried there, plot Number 60.
