Old message but I have very little information on the family and now that church records are on line you may already have this
John Shea and Margaret Fenton married Jan 21, 1845 in Ballyferriter
Children from baptismal and marriage records
John: July 2, 1848, Cuan, Ventry
Patrick: Oct 21, 1849 Cahertrant, Ventry
Mary: Mar 25, 1851 Cahertrant.
Mary: Mar 29, 1854 Cahertrant
The 2 Mary's could be because the 1st died or the wrong name was shown on the baptismal record.
Mary married John Ferriter, of Caherquin, Mar 11, 1881, Dingle
Thomas: Dec 19, 1855, Cahertrant
Joseph: Apr 7, 1858, Cahertrant, Married Ellen Lynch of Kilfountain, Feb 14, 1893, Dingle
It has been a long time since I captured this information, but I have been pursuing the Fenton's including those from Cuan for a long time
Hope this helps
