Coming to Ballina this summer

We are planning to be in Ballina (Crosmalina) July 31 - Aug 2 this summer and would love to make a local connection. My relative was Dominick O'Donnell/Donally born 1783 Bengerrew, Crossmolina, Mayo. He married Catherine Mayock about 1815 in Crossmolina. We have the birth records for two of the children (Michael and Dominick). We are also related to Edward James Kelly and his wife Mary Neary from Mayo but don't know the parish.
