Rymer, regarding my mother's family (the Wades), Winnie Wade was my auntie and her son Maurice my first cousin (he was a member of the old Greater London Council many years ago). He has two sons. My grandmother Josie Wade did have the three siblings you mention. My first cousin still lives near Cashel. My mother is the last surviving child of Josie Wade and she married James who was also a resident of Thomastown (in fact he lived on the farm by the Theobald Mathew statue). I am not sure if I am a distantly related to Shane Breen but it seems highly likely.
