thanks to all 3 of you.

and such speedy response.
No, I have not looked at Monumental Inscription or purcase records. Maybe there is a purchase record for " Bridgewater Farm " in Cambridge.
I'm not sure when Margaret Corcoran married John, only that he was living in Gurtmakaar, Ireland at the time. I estimate between 1872 and 1879. I have his birth as abt 1852 , but not confirmed.
I have found a John O'Dwyer arrival in Sydney, Australia 27 July 1907.
( possibly on way to N.Z ) .............from the NSW, Australia, Unassisted Immigrant Passenger Lists- 1826-1922.
So the Divorce of a Margaret and John between 1908-14 could be my John.
Have John's death as 14 Aug 1929.
Have Nora Ann being born at "Bridgewater Farm " Cambridge, N.Z. in 1887. need confirmation of birth details. Married John Price Davies ( my Great Grandfather ) on 24 Feb 1915 at registry office, Auckland. Divorced 11 June 1926 in Auckland.
Possibly had a sister - Mary , born 1879 - not sure where, ( so 5 children between 1879 & 1895 is a possibility if this works out ) On 25th June 1902 She married James Phillips at Auck Registry Office. Mary died 13 April 1915 in N.Z. ( In Cambridge I believe ) need to know if Nora & Mary were sisters.
Anything you can offer would be greatly appreciated.
