Hello,

There were a decent number of Irish companies from GA:

Irish Jasper Greens - Co. B, 1st GA (Olmstead's)
Emmett Rifles, Co. F, 22nd GA Heavy Arty
Irish Vol. Guards - Co. E, 1st GA (Olmstead's)
Irish Vol.s - Co. C, 5th GA
Montgomery Guards - Co. K, 20th GA (possible Irish)
McMillan Gds. - Co. K, 24th GA
Telfair Irish Grays - Co. H/A - 25th GA

There are probably more of them.
