Terrence, If you Google "Patrick Fennell", among the results there is a tree on MyTrees.com. Alternatively Google MyTrees.com and search for him. You can see some data on dates and children, but no locations. And as it's a pay site you would have to join to see full data or to contact the submitter. But you may have that data already. I could see nothing for Patrick O'Callaghan. Unfortunately, you didn't give any data on his age, death, spouse or children. It would take me hours to look it all up, when you probably have it. I note you said they came from England. Were they perhaps there for 1851 census? Were any children born there? Peter
