Welcome to Ireland Reaching Out!
I located the civil marriage record for Patrick and Jane https://civilrecords.irishgenealogy.ie/churchrecords/images/marriage_returns/marriages_1871/11335/8160204.pdf
I found a transcription of the 1879 baptismal record for John.
Did not find a baptismal record for Kate. Also, did not find a death record for Patrick.
I'm still trying to locate the 1911 census record for the family and Jane's death record
