I believe these are all Church of Ireland as there was no civil registration of RC records till 1864.All records before that both baptism and marriages are only available from the Parish.
North Riding and South Riding Tipperary both belong (separately) to a Irish History Foundation that has an online data base, it is not for profit but fees are charged:
Checking the Parish Terryglass it appears to be a Church of Ireland parish has records from 1809-1911 for baptisms,
same for marriages and deaths recorded (rare)1809-1982(yes that is correct)
The Parish of Borrisokane RC records from 1821
Church of Ireland baptisms/births from 1877, marriages 1845-1911, deaths 1877-1985 (rare)
Roscrea (including Kyle to 1846) has RC records from 1810-1880 for baptism and marriages.
Terrylass is also a Parish, a Townland and a Village
in the Poor Law Union of Borrisokane. There are 0 Heffernan's in Griffith Valuation 1852. www.failteromhat.com
(a version of Griffith Valuation) does have a Collins as follows:
William Collins, Parish Terryglass, Townland of Clooninihywww.askaboutireland.ie
has a more indepth version of Griffith Valuation.
Patrick Galvin, Parish of Terryglass, Townland Turavoggaun, Union of Borrisokane tenant of Thomas Brereton
7A house, outbuilding and land 7.1.32
7B land, 0 acres 2 roods 0 perches
William Collins, Parish of Terryglass, Townland Clooninihy
tenant of Thomas H.B. Watson, Poor Law Union Borrisokane
15 land 17 acres 3 roods 30 perches
19b house and land 8.2.6 (is sharing the land portion 1/4)
Heffernan's none in Parish Terryglass but in a variety of
parish's one is the Parish of Borrisokane.
Terryglass being in the Union of Borrisokane which makes it within 12 miles of the town of Borrisokane so not so far
Terryglass is a townland in the Parish of Clooinihy, that parish name doesn't appear in the History Foundation, North Tipperary records.
Generally marriages took place in the bride's parish.www.familysearch.org
for births, marriages and deaths
from 1864 are listed.
There are several William Collin deaths, the earliest birth year is 1802 followed by 1816, 1824, 1819www.census.nationalarchives.ie
You can find a variety of information at both these websites, sometimes baptisms, tithe records, gravestone inscriptions and pictures etc.
ps The telephone book for Tipperary has 80 Heffernan in at least one in Borrisokane (other places too)100+ Collins also some listed in Borrisokane, 80 Galvin's also Borrisokane. Too many for me to keep going but pick a few and send letters, stamps are inexpensive genealogy
