Finding wills and land ownership records in Co. Tipp for 18th and 19th c.

An ancestor Martin Treacy lived in Bawnmadrum, Bourney, Co. Tipp. in the late 1700's. He received an annuity from English landowners James and Elizabeth Hutchinson beginning in 1786. I have a copy of that document. I believe Martin used the money to purchase land in Bawnmadrum North.

How can I obtain a copy of Martin's will, probated 1796, and also his son's will, probated 1831 (also named Martin)? I have the index records but not the actual wills.

Where do I look for land ownership/sales records in the late 1700's thru late 1800's/early 1900's, for North Riding Tipperary?

Thanks, Celeste
