My great-great-grandfather was:
Michael Hartigan born: approx 1839, presumably in Parteen, Co. Clare
married:
Norha Kain born: approx 1843
both in Co. Clare, Ireland
Their son, Martin Hartigan born 1865, definitely Parteen, Co. Clare, came to New Zealand and married approx 1902 to Mary Ellen Murphy.
Martin Hartigan born: 1865 as above
died: 10 Jan 1914
Dyerville, Martinborough, New Zealand
married in 1902
Ellen Mary Murphy born: 1881, unknown birth place, presumably Ireland, she married an O'Farrell, next Martin Hartigan, in:
Ohau, Southland, New Zealand
they had three children, but I only know of my grandfather who was:
Martin John Hartigan born 1907 died 1984
married to
Mary Ellen Lundon born 1904 died 1988
they had three children:
The trouble I have with the Hartigan's in NZ is I don't think the place of marriage for Murphy to Hartigan is correct. I believe there were 2 Hartigan family's in NZ around this time, one in Ohau and the other my direct line. If there is a connection, possibly brothers.
I believe that there is a Patrick Hartigan, elder brother to Martin who emigrated to Australia from Parteen at around the same time. Bit of a coincidence if unrelated given dates and that Parteen was not a huge place such as Dublin. I have no details on the Hartigan's in Ohau or South Island of NZ - nor do I have contacts on the Patrick Hartigan line to Australia.
Hope this information is at least a little useful, good luck and look forward to hearing what you think,
