Looking for Barry or Cosgrove families in Tallow, Waterford.

Looking to connect with any Barry family living in or near Tallow.

I am descended from John Thomas Barry, born 1820 in Ireland and who emigrated to Prince Edward Island, Canada about 1842.  His parents were Thomas Barry and either Bridget Cosgrove or Cameron as the surname was very difficult to make out in his marriage record here in Prince Edward Island.  Thomas Barry was the son of Richard Barry, wife unknown.  Thomas had a brother, John Richard Barry born circa 1790 in Ireland and he emigrated in 1812 first to Newfoundland, Canada and then moved to Prince Edward Island in 1815.  

Thomas & Bridget had a daughter, Elizabeth Barry, who had emigrated to the Boston area of USA.  She died shortly after hearing that her husband had been killed in an accident.  She had a brother, Francis Barry who served with the military in the far east.  

John Richard Barry had sons named Benjamin and John Barry.  My John Thomas Barry had two sons named Richard and Francis Barry so they must be family names passed down through the generations.  

We are planning a trip to Ireland in August and I would like to reconnect with any Barry family living in or near Tallow.  If somebody knows anything about these ancestors, please email me at cudfox@hotmail.com.

Thank you,

Mary from PEI, CANADA
