Searching for Slattery Relatives in Lisronagh

My name is Mike Slattery from Hays, Kansas, USA.  My wife and I are planning a trip to Ireland for April 3 - 16, 2013.  I am hoping to make conatct with Slattery family relatives who originated from Lisronagh, County Tipperary. 

James Slattery married Mary Burke and they were the parents of Patrick John Slattery who is my Great-Great-Grandfather.  Patrick John Slattery was baptized on 26 June 1839 at St. John the Baptist Catholic Church in Lisronagh.  On previous trips to Ireland I was able to obtain the baptismal records for Patrick John and his siblings.  I also have the names of baptismal sponsors for each of the children as each of them were baptised at St. John the Baptist Catholic Church in Lisronagh. 

Children of James and Mary (Burke) Slattery:

William Slattery:  Baptised 28 March 1833 and died about 1845 in Lisronagh.  NOTE: I would like to be able to find the headstone for his grave.

Catherine Slattery:  Baptised 28 January 1835 and died about 1852 or 1853 at age 17 or 18. NOTE: I would like to be able to find the headstone for her grave.

Margaret Therese Slattery:  Baptised 14 September 1837 and emigrated to Australia.

Patrick John Slattery:  Emigrated to USA and died in Kansas, USA.

Johanna Slattery:  Baptised 31 August 1842 and emigrated to Australia

James Slattery: Baptised 2 August 1846 and emigrated to USA and died in New York, USA.

I am also hoping to find the land James Slattery rented in Lisronagh based on the 1850 Griffiths Valuation for Lisronagh, County Tipperary, Ireland (Ordnance Survey Map 77).

I look forward to any information you might be able to provide me.  Thank you!
