Hi Edenhope,
You say........
It is disappointing that the RC baptism records for the Parish do not go back further than 1834.
Most Churches were allowed to be built or re-built around 1830 onwards. That's why we only have records from that era, unless you were in the cities.
Killadangan, parish of Killodiernan…………………same areas are Monsea, Annagh, Annaghbeg and Ballydrennin.
My Gran was from here and depending on what records you view the Parish, townland and area, they are listed under different names.
There are lots of families of Gleeson’s in that area and it borders with Finnoe.
Going by the Tithe records the area is Finnoe, and there is a Tim Gleeson in Finnoe.
This is a search by Gleeson and Tim* and Tipperary (most of the areas below Finnoe are not near to where yours are from, check these place names on a map)

I did look in the registers online site for Killodiern and could only see a Timothy Gleeson and Judith from Kildangan having children Baptised from 1832 to 1840ish
Was the name Sarah Mullaly on an original document?
Do you know if he has any sibling names?
The place you mentioned Kiliniska ……………..I did see this name………….. in Poland.
Klininick another close name is in County Wexford.
BUT………..
Could this place be Killoskehan it's between Templemore and Borrisoleigh.
Near to Nenagh and as it was in the local newspaper the Guardian (my favourite paper) it must have been close by.
When we drive around the area I take note of the townland names from the SatNav, as I could never find them!
In Griffiths Valuation Thaddeus is listed, if you look at the top one, Cornelius Gleeson, you will see he rented land owned by Mary Toler Minnett, they lived on a large estate near to where my Gran lived.

Hope this explains a few things.
