Welcome to Ireland Reaching Out!
The civil marriage record is here (second record) https://civilrecords.irishgenealogy.ie/churchrecords/images/marriage_returns/marriages_1868/11475/8217988.pdf Names of fathers are shown along with where the bride and groom were living. John was 27 and Jane 21.
I found a daughter Jane born in 1870 (seventh record) https://civilrecords.irishgenealogy.ie/churchrecords/images/birth_returns/births_1870/03335/2222619.pdf
I will look for more records and get back to you.
