Kay, is there an LDS Family History Centre anywhere near you? If not too far away it is a simple process to order the films to view, and it would/could be a huge help to you to look at John Kelly's marriage to Jane Ritson [LDS film no.0106192] and also William Myrea's will [MYLREA, William 1823 Mal E [no.] 1 [LDS film no.] 0106423.
Film 0106192 has Christening, marriages, burials 1849-1883 from Malew.
Find the worldwide FHCs in the phone book under "Church of Jesus Christ of Latter-Day Saints" which is open to all - ring them to get the non-member opening hours. The staff there are very helpful, and the film ordering cheap.
