Hi CATHI . . .
Welcome to Ireland Reaching Out . . and . . Tipperary County . . .
Not sure if can be of much kelp to your search . . given . . the little info.you start with . . . however . . .
I started my search on " Roots (paid). . looking for Ed.Meagher b.1831 . . Thurles area . . . Moycarky / Galbertstown . . . (see below)
Roots . . tell me . . 10 Meaghers were born in Tipperary . . between 1826 - 1836 . . . of which TWO only look hopeful . . (below)
------------------------------------------------------------------------------------------------
Edw.MAHER . . .born 1833 . . is the ONLY . . . MOYCARKY . . . showing . . . ( note surname spelling )
Edw.MAHER. . born 1830 . . . THURLES . . . is a possability . . . ( note different surname spelling ) . . .

So next . . I looked for a MARRIAGE of the possible Parents .. . . i.e. Martin and Bridget . . and found (below)
This date . . 1832 . . . confirms EDWARDS (Moycarky) birth in 1833 . . .

Local Parish CHURCH records . . . for those times . . . see . . . https://registers.nli.ie/parishes/0248

I looked for . . but failed to find . . . a Marriage of Edw. and Henna Shanahan , , ,
______________________________________________________________________________
So . . next I struck GOLD . . . when I searched for Pennefather . . (see below) 1805 Moycarky . . .
This find . . . would appear to cement . . the Moycarky location of Edward and Catherine . . before EMIGRATION . . .
__________________________________________________________________________________________________
Next I searched for a MARRIAGE for Edmund Pennefather . . . and . . ( Catherine Martin ) . . . with NO success . . BUT . .
when I leave out the ( Catherine Martin ) . . . I get the Marriage in UPPERCHURCH . . ( see below ) with BRIDE . . Anne MAHER . . .
This looks hopeful . . Upperchurch is in that location . . and the Surname Pennefather is very uncommon . . .

This is a TAX roll from 1823 - 1837 . . . when I check Pennefather in Tipperary . . I find 60 listed . . no way to certainty .

With the above serch site . . I tried Meagher . . . hundreds showed up . . .
As you may be aware . . . in Tipperary . . . Meagher is interchangeable with the spellings of Maher, O'Meachair. Mara etc. .

Best I could do . . .
