Aftermoon..
after searching the New ZealandBDM website I found the following
Matilda Kennedy marries George Turkington .. 1917
Margaret Maxwell Kennedy marries Herbert harlton Woodbridge .. 1917
.. then after searching the New Zealand electoral roll further
.. 1919 to 1946 .. at various addresses around Wellington
George Turkington - railway clerk
Matilda Turkington - married
.. in 1946 several other Turkington names appear, including a Keith Kennedy Turkington at same address as George and Matilda
.. in 1949 a Gordon Maxwell Turkington appears at same address as George and Matilda
.. by 1969 George and Matilda appear together at same address for last time
.. 1972 to 1981 .. Matilda is listed as a widow
This is as far as the Electoral records go.
I have Margaret Maxwell Woodbridge , nee Kennedy at a different addres from 1919 to 1944 to her death .
So maybe Margaret and Matilda are sisters ..

I cannot find any info on when either girl arrive in NZ..
All 'food for thought ..
Cheers
Karen
