Lots of information available online. There seems to be a large number of Sessaregos in Hereford district (England) who may or may not be connected. In the 1851 census there is a Joseph Sessarego born c1835ish in Italy (see FamilySearch). Meanwhile here's a bit on the family of Joseph Sessarego & Hannah Murphy in Cork.
