Hello Sheila, are you searching for the family here in NZ or for John's siblings descendants in the USA? I was married to Des's son John jnr and your brother Patrick was our witness. I also lived next to Aileen for about six years. From searching the LDS Familysearch on the web I found out that John's mother was probably Bridget Donellan. Mary Jo on this page has ancestors from Clare, there must be a connection somewhere.
