Margaret Rice Queenstown Ireland photo

I have seen a photograph online in a number of sites of Margaret Rice and her 5 sons. I am working on a website for the Northern Ireland Tourist Board at the moment and I am filming a piece on the Last Port Of Call in Cobh (Queenstown) next week.
I am looking for the person to contact in regards to using the photo of Margaret and her sons in the film.
Anyone know who I can talk to about it
