Oh my word! That is amazing. Thank you so much!!
So Austin (Augustine) Harkin does actually exist! And I have a location in Clare.
And Anne (Nancy) and Denis O’Loughlin’s marriage fits too - just before coming to the land of promise.
I’m wondering if the last birth above is John? (Hard to say definitively).
On Anne’s marriage certificate to Michael Moroney she list 2 living and 4 deceased children to prior marriage(s), and on her death cert. it lists her children Honora and Austin, then James and John as deceased.
I have a birth entry for James in Australia (father Denis) so perhaps Michael died as an infant and because he was prior to Honora, she didn’t know about him (and another sibling that has not been found - perhaps the earlier birth of Norry?) so not included in the death certificate.
