Seeking Relatives and Ancestors Graves

Iam visiting Ireland at the end of May andI 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, hermaiden name was McCormick. I have also attached a copy my Father's birth certificate and information from the1911 census.
