Just adding updates to my query of Dec '99.
My gr grandfather, Patrick b 1849, emmigrated to New Zealand c 1869.
His parents were Dermitius(Jeremiah) O'CONNOR married Margarita FLAHERTY on 6 Feb 1838, at St Mary's Catholic church, Castlegregory. One of the sponsors was Maurice O'Connor. They had six children:- Ellen, Michael, Patrick (most probably died), Dermitius, Patrick (most probably died also), and Patrick (my gr grandfather)
The townlands on marriage/baptism entries are both shown as Castle (Castlegregory)
Would love to hear from anyone who recognises these names.
