Welcome to Ireland Reaching Out!
fourth record on this page has the May 17 1886 civil marriage record https://civilrecords.irishgenealogy.ie/churchrecords/images/marriage_ret...
Fathers of the bride and groom were Matthew Bolger and John Hayes.
Matthew Hayes was baptized January 25 1887 in Tullow.
I looked at the baptismal records on the subscription site Roots Ireland and the parish register and it would appear that the 1859 baptismal record is the correct record for Margaret. There is an April 7th 1863 Margaret Bolger baptismal record where the father was Patrick and the mother was Mary Murphy. https://registers.nli.ie/registers/vtls000634592#page/45/mode/1up
Here is the register for the 1859 record which shows Matthew as the father. (The 1859 register was faint). https://registers.nli.ie/registers/vtls000634592#page/15/mode/1up
The 1859 Margaret had the following siblings: Alice 1861 Marian 1864 Edward 1866 (died young?) Edward 1871 James 1872
Matt Bolger and Mary Murphy married October 24 1858 in Ballon RC church. Witnesses John Bolger and Jane Neill
