Hello again Barbara!
I found an April 24 1868 death record for a Patrick Roarke from Derrinkip. He was 69. He was a widower and the informant was Henry Roarke.I located this record on the subscription site Roots Ireland. As you likely know the free site www.irishgenealogy.ie only has index records for deaths from 1864-1870 although we expect the images for these years in the near future.
I did not find a record for Bridget and possibly she died before 1864 when civil registration started.
Did your Patrick Roarke/Rourke have a son Henry?
