Vonny:
Welcome to Ireland Reaching Out!
I located three baptismal records on Roots Ireland but the first of the three is questionable because of the townland and the maiden name was shown as Keegan. The 1867 and 1871 records look valid.
I checked the 1901 census for Butlersbridge and did not see any McKeegan families.
