Hastie

I'm looking for information regarding Blanche Hastie who married Ian Mcintosh in 1932 and has one child Beverley who is now deceased. Ian Jock was a captain in the australian army at one stage and also a cabinet maker. They lived around the Balmain area Sydney NSW.
Blanche married again to William Haining and has 4 more children.

I can not find anything about Blanche's first family. I know her father died and her mother remarried. Her mother's name was Margaret and was Scottish. They lived on the Northern beaches.
