Hi Pat, thank you so much for taking the time to reply. I've had a quick look at the very handy website and list of burials you've pointed me to. I'm afraid I'm not very familiar with Dundalk (I live in southern England) but I gather that its local graveyard is the Castletown one plus the parish church graveyard for earlier burials? I know that their father was buried in the Old Castletown Cemetery so as a starting point assumed that his two daughters may have been buried there too? On that basis there is only one suitable candidate but she is already listed on 'Find a Grave' and the dates are wrong.
If anyone is aware of other burial sites that a Dundalk resident (living in Crowe Street in central Dundalk) could have been buried in the 1850s or 1860s, I'd be very grateful for that information?
Another cheeky question if I can? Would it be the usual custom in Ireland in the mid to late 1800s for a marriage to take place in the parish of the bride rather than the groom?
Thank you all again for your help, Andy
