Seeking Relatives and Ancestors Graves

I am visiting Ireland at the end of May and I would like to locate the grave of my Grandfather Edward Ryan and find out if there are any surviving relatives still in the area, from either my Grandfather's or my Grandmother's families. I am aware that my grandmother came to England in approximately 1900 with my father and 3 other children. I have attached my Grandmother's baptismal certificate, her maiden name was McCormick. I have also attached a copy my Father's birth certificate and information from the 1911 census.
