DNA results have sent my research in a different direction I find that I now have strong links with the following people and it may well explain why I have never been able to find my great grandfathers (James Butler born 1853) birth in Queens County.
Mary Cotter born 1811 Aghanda Cloyne Parrish
Daughter of Edmond Cotter born 1771 Cork and Ellen Twomey born 1774 also Cork
Mary married John Walsh born 1805 in Cork they had a daughter Mary Ellen born 1852 in Queenstown Cork and she married John Joseph Byrnes from Tipperary and went to live in the USA.
Other names associated with this line are
Elizabeth Hickey born Tipperary 1824
Edward Bryne born Clonmel Tipperary 1811
John Byrne born Clonmel Tipperary 1781
I would be very pleased to hear from anyone who links with any of these names or who has information on any of the Butler families of Cork
