Hello,
George Waters marries Abigail Kelleher 14 Oct 1845, John Kelleher and William Waters witnesses, performed by D. Mahoney. page 47 of Cloyne/Aghabullogue registers: nli.ie 05007/06.

Abby's will calendar is among 18 Waters wills recorded: http://www.willcalendars.nationalarchives.ie/reels/cwa/005014914/005014…
Wm Waters of Caum age 65 dies in 1871. http://www.willcalendars.nationalarchives.ie/reels/cwa/005014894/005014…
Griffiths Valuation has a William Waters in Derryroe, Aghabullogue in 1852. There are 90 Waters in Cork. http://www.askaboutireland.ie/griffith-valuation/index.xml?action=doNam…;
I have not extended my Kelleher family searches to Macroom beyond scouring the Aghabullogue registers at nli.ie. There were some Kelleher/Waters families in Donoughmore parish, notably Denis Kelleher married to Catherine Waters with children from 1816 to 1825. Also a John Kelleher married to Catherine Waters in GLantane circa 1859, later of Beeing/Bweeng. Maybe some of these links help. Happy hunting.
