John Kinvig who married Miss Croaghan was a brother of my GGGrandfather William Kinvig of Balthane, Malew. I don't have full data on John but he was the son of Richard Kinvig and Eleanor Cooil. My notes are from my aunt's recollections, but I have John and Miss Croagan having Elizabeth, married Edward Quayle of Ballamoddha; Ben who married Sarah Eleanor Shimmin and left a son Stephen; another daughter who married a Gill or Gale of Port Soderick; another daughter married a Mr. Jackson and had a son Victor Alec (d. 1966) who married Freda. Most of these people are Southside if not all. Sorry its as it came from the horses mouth.
