Hi Spark,
You may get some information on the head of the family if you check the Griffith Valuation tables which were produced around 1855 - 1865 for most areas of Ireland. They are a list rateable values of properties and only list the head of the family living in the property. I managed to find one of my ancestors living in Clare Galway ( 8 miles from Galway City ) this way. The tables are normally borken down into townlands within the appropriate area.
