I don't have any census info , but I do know that my grandfather William Dacey had an older brother Patrick F. Dacey. Patrick was born about 1852 in Rosscarbery, Co Cork. His family then came to Massachusetts. He lived most of his adult life in Lexington, MA.He died on August 22 1934.I have a copy of his obit that lists children, etc. Could this be the same Patrick?
