Hi . . .
Welcome to . . . . Ireland Reaching Out. . . and . . . Tipperary County
That far back (1790) is very diffacult in searching records for Ireland . . .
In searching . . my first discovery . . ( see below) ...
Michael Cunneen . . born 1815 (diff) . . in DROM. . . BUT . . to William and Winnifred (diff)

If you have availability to view Ancestry . . . go to . . .
https://www.ancestry.com/family-tree/pt/PersonMatch.aspx?tid=111457280&pid=202187385829&src=m
These are Family Trees (Public) . . . to do with the same Cunneen Family . . .
Mothers Maiden Name . . . would appear to be " SHEEDY" . . . .

So. . when I search for MARY SHEEDY . . . I find TWO (only) at that time . . . in ALL Ireland
1) (see below)
2 ) (see below)

The MARY above . . . . is very UNLIKELY. . to be Mother of yor Michael (1812 ) . . .William . . .(1816 )
BUT . . could be the birth Mother . . (possibly) . . of the MICHAEL ..born DROM 1815. . .

WILLIAM ... born DROM . . . 1820. . . (see below)

NONE of the above is . . . similar . . .to your query . . . BUT . .
Maybe . . it might be of some help to your continued search . . .
Best I could do . . .
Cheers . . . Eamonn
