I see you already have quite a lot of info on your MyHeritage website.
There are at least 4 other very informative websites on MyHeritage.com.
Margaret Bennett has a great deal of information (dates, places, siblings, parents etc) on Blanche on her 'Bennett Website' on MyHeritage including a photo!
Also, there at least 3 other people with similar information. Too much for me to transcribe here (but I will help further if req'd)!
Dallas Hann has on his website that they were married in Hawera, N.Z. but does not give a date.
This is what my N.Z. research found - Mother: Blanche and Father: Dudley Barnard.
N.B. Some of the above family trees do NOT have this information or it does not match. My sce: www.bdmhistoricalrecords.dia.govt.nz
1. Dudley Jack Jordan b. 17 May 1914.
2. Richard Coles Jordan b. 14 Dec 1907.
3. David Clifford Gibson Jordan b. 10 Mar 1909.
4. Clara Blanche Jordan b. 24 Apr 1912.
5. Doris Kate Jordan b.1 Jan 1911.
Their other 2 children were probably born between 1915 and 1919.
I didn't find anything on the Brunold children.
