3 Generations of Casey’s

Since posting the following message a few hours ago I have found my Great-Great-Grandfather, Thomas Casey in "Ireland, Civil Registration Inexes, 1845-1958. However, the online site only references Registration District: Lismore, Volume 4, Page 469, FHL Film Number: 101591.  I'm really curious to know whether this record gives the site of his burial. Anyone have access to these films/records? Anyone know how I can access them from Minneapolis, USA?  Thanks!

Thomas Casey (1779-1882) and Ellen Phelan Casey (1795-1883) from Ballyduff Upper were my great-great grandparents. They had at least two children, presumably more. William (1835-1883) was my great grandfather and emigrated to America in the early 1850s. Another son, Maurice (1836-1908) remained in Ballyduff Upper. I know from Maurice's great-grandchildren in Ireland, my third cousins, that three generations were buried in the same family plot in the general vicinity of Ballyduff. These would be: Thomas Casey (dec. 20 October 1882) and Ellen Phelan Casey (dec. 7 July 1883); their son Maurice Casey (dec. 1 Dec 1908) and his wife Mary Daly Casey (dec. 5 January 1905); as well as Maurice and Mary's son Michael (7 April 1881 - ? December 1922). Locating this 3-generation Casey plot would help me document, and some day return to pay my respects at, the site of my great-great grandparents' burial. I'm eager to hear any and all suggestions as well as any information may have to share. Thank you.
