I can guide you a bit, it is essential you try and learn how to use a free website. You can copy the information from a marriage handwritten certificate from
https://civilrecords.irishgenealogy.ie/churchrecords/captcha.jsp if you don’t find it under church records change to civil records, patience rewards you.
Its for your personal use otherwise read their rights. or buy a very cheap copy. Search for William Petherick marriage 1904 to Margaret G(raham) Curry , you will only find Ms Curry and her father by looking. then by adding in anything else eg
www.emeraldancestors.com and
https://www.familysearch.org/ark:/61903/1:1:FY8M-124 Start making a familytree you should find William Petherick has a father William with known occupation but no location.

I tried having never heard of any 1861 census details unless it is a query for a pension etc
GenesReunited has
William Petherick 1896 Ireland ...
the rest 6 are all in Co Sligo.
changing to the Graham family I ended up in confusion
changing to the Curry family I could not find a painter in census or quick look at one street directory
The Presbyterian church named in the marriage details might well hold records of births?
Good luck onwards
