I was asked by Jane Halloran Ryan to help you with your query.
From the beginning I have a problem with the Townland you gave for Patrick and family. I cannot find a Townland with the name Danganmore in Bandon or anywhere else in Cork County. either on the Census or any of the genealogy websites Would you please send me a link to the Census entry you referred to where Ellen and family were found.
I need that or a link to anywhere Danganmore Bandon is mentioned before I can even think about a search which will be thorough.
