Kerri, I saw your posting regarding Dwane in Limerick County.Unfortunately at present Limerick Co does not have an active Heritage Unit. These centres house the Catholic records.They are non-profit entities charging a fee to search names that you provide. Tipp does have one. There I found my gggf Jeremiah Croker, having his 1st child Judith being baptised,1847 in Lattin, Tipp. The sponsors were, Simon Dwane and Mary Dwane! This area is only 2/3 miles from Limerick County where I have found other Duanes, Dwan's, etc. Good Luck and God Bless!
