John Lyons & Catherine Carver had 3 children 1858 - 1865, so does Catherine Nash's 1865 b.c. give Catherine Lyons as the witness?, and does it say she was nee Carver and a sister-in-law. I never found the actual marriage in the Ballyclough records, but I do have that of William Lyons to Honora Sullivan in 1846.
If you get the 1851 m.c of Michael Nash to Ellen Lyons, I would love to know any details on it, please.
