Hi Anthony,
I would recommend you subscribe to
www.rootsireland.ie for a day where you can find the marriage record of John and Bridget, as well as what would appear to be Bridget's baptismal record and those of her siblings. Using the names and dates on their baptismal records, you will then be able to search for their own marriage records and then search for them in the 1901 and 1911 census returns available at
www.census.nationalarchives.ie.
Although we could not locate John's baptism on www.rootsireland.ie (we don't yet have records from every Church), we did find some marriage records where the father was a William Hayes which may be those of his siblings. We also found a William Hayes living in Carrickfergus on the 1901 census with his married daughter and her family - this could be your ancestor.
While you are in Ireland, you may wish to visit the Public Record Office of Northern Ireland (www.nidirect.gov.uk/proni) which holds the majority of Church registers for the north of Ireland. You may also wish to book a consultation with one of our genealogical researchers in our offices in Belfast who can guide you further. You can do this by emailing
enquiry@uhf.org.uk.
Good luck with your search and have a wonderful time in Ireland,
Kind Regards,
Gillian Hunt
Research Officer
