A long post, I hope you aren't as cross-eyed when you finish with it as I am

I think Peter Fegan who married Bridget McGivern might have been born before 1812.
They married in 1832 as you said. Here is the parish register entry:
Clonallan Parish
February 28, 1832, Kilbroney Parish marriage register
Peter Fegan was married to Bridget McGivern in presence of Bridget McGivern and Jas McGivern
P McEvoy, Pastor of Kilbroney

They had children until 1849, assuming rosdavies.com is correct. There is no reason to say it isn't, I just didn't look for the baptisms.
Did she live a full life or die in childbirth? If a full life, then say Bridget was maybe 40 to 45 when her last child was born. She would then be born about 1809 at the latest. Peter would probably have been older. But maybe she did die young, and you can't go by that.

He might be, but I actually don't think he is either one of them. The land was in his son Bernard Fegan's name when Griffith's Valuation was taken in 1863-4 (see below), so there is a good chance his father Peter died before that.

Bernard married Eliza Crawford May 3, 1859, as you know. here is the parish register:
May 3, 1859, Clonallon Parish marriage register
Bernard Fagan and Eliza Crawford
witnesses: James Flanigan and Eliza Crawford

I've seen a lot of cases where the son didn't marry until after the father died, so maybe Bernard's father Peter died shortly before 1859. There are no burials for Clonallan Parish at nli.ie, so it will be difficult to figure when he died. But are the burial registers anywhere else?

Are you looking at this man as a possible father of Peter Fegan, husband of Bridget McGivern?
from
http://rosdavies.com/SURNAMES/F/Fegan.htmArthur FEGAN . Kilbroney husband of Saregh Ferin ; father of Mary bpt. 14 Nov 1808 at Kilbroney Catholic Church PR
Arthur FAGAN . Kilbroney husband of Saragh ..... (can't read) ; father of Peter bpt. 28 Jun 1812 at Kilbroney Catholic Church
Arguments against this man being the father of Peter Fegan who married Bridget McGivern: his children were baptized in Kilbroney Parish, not Clonallan.
Arguments for him: I didn't find any Fegans in the Tithe Applotment lists (1834) for Aghnamoira Townland, Clonallan Parish. Maybe they moved there between 1834 and Griffith's Valuation.
You'd have to see what happened to this Arthur and his son Peter. are they on the later land records in Kilbroney? If so, did a son Peter take the land from him later? If so, then he is not your man, because your family was in Aghnamoira by 1864.
He could be this man in kilbroney parish, on the Tithe Applotment Lists, 1834, to give you a start of where to look:
Fegan, Arthur Townland: Knockbarra

Here is Bernard's civil death record
Newry Registration District
April 10, 1907
in Aughamoira
Bernard Fegan, 74, farmer, cause: probably apoplexy, no medical attendant. informant: Kate Fegan, daughter in law, of Aughamoira, present at death

Here is how I traced the land backward. You have to start at the bottom and work up. You can see the land change hands toward the end of Bernard's life. I don't understand why it went to Joseph Crawford for a few years before going to his son Patrick, but this was the only Bernard in that townland in the Revision books:
