The townland would be Blackrath and Athgarvan in Greatconnell civil parish in central Co. Kildare. It looks like you have the baptismal record for Andrew. The subscription site Roots Ireland had a brother Patrick baptized Christmas Day 1857.

There was also a record for an Ellen Byrne in 1855 in the Athy RC parish. Also, I located an 1850 marriage record in the Suncroft RC parish. See below.
There were also Byrnes in the townland in the 1901 census.
