Tobermory on Family Tree Circles

Looking for information on the following persons:-

Margaret Shea born RC Parish of Dunnamaggan July 1834
Patrick Shea born RC Parish of Dunnamaggan June 1836
Mary Shea born RC Parish of Dunnamaggan March 1838
John Shea born RC Parish of Dunnamaggan April 1844
Richard Shea born RC Parish of Dunnamaggan May 1847.

All baptised in Dunnamaggan. Parents: Richard Shea & Mary Butler. The children's eldest brother was James (named for his Grandfather) and I am his great Grand daughter. My family - including my own Grandfather, James' son - knew nothing of the fates of these children, since James left Ireland for Wales in 1854 and had no further contact with his home village.
