I recently uncovered the Concannon surname among my Galway roots. Have ggg-grand Mary Concannon, est. birth 1825, of Inishbofin, marrying ggg-grand John Heanue of Derryinver. Their children were Brigid, Mary, Joe, gg-grand Honore, Stephen and Joe. Both Honore and Stephen married into another Heanue clan in the Cloonluane area of Renvyle.
Can anyone shed any light on the Inishbofin Cocannons?
