St. Salvatore churchyard

Hello,

From my genealogy research my great grandparents are buried in the churchyard at St. Salvatore church. I wrote to the Rev. Capper from the church asking about the cemetery. I am interested to go there and was inquiring regarding if the churchyard is open to the public, any particular hours? She kindly responded suggesting i go to church there on Sunday. It's not on our itinerary to be there on a Sunday. Does anyone know where i can get this informaion? I'd hate to go there and not be able to enter. We will be in ireland in May

Thanks in advance for any info.
