Im not aware of Ellen, but have details on her sisters Catherine Theresa and Annie who were christened in Bennetsbridge between 1865 and 1872, so there plenty of capacity for more children.
Edward was the brother of my ancestor James Foley who married in Annamult in 1854 (outside Bennetsbridge) came to Australia straight after. James and Edward were the sons of Denis Foley and Ellen Mangan (Mangin). Denis in turn the son of Daniel Foley and Mary Campion was christened in 1788
Happy to send the family info I have.
