I can confirm James C (ch 18 Sep 1743) was married to Margaret Faragher on 23 Jun 1765 at Marown. They had 10 children James, Ellinor, Ann, William, Margaret, Thomas, John, Robert, Joseph, & Charles.
Your tree follows Thomas b 1780 who married Elizabeth Moore on 13 Sep 1803 @ Lezayre and moved to England about 1822
My family follows John C b 1783 who married Ann Corlett.
Some records belive James C re-married a Catherine Kneale in 1792 but I belive John & Margaret moved to Lezayre and both died there in 1813 & 1823.
I have details of their Wills should you be interested.
