Hi Helen,
I worked for Brian Harold Ivimey during the 1970's when he ran an agency for the NSW Government Insurance Office. He was known as Harry and was married to Val and at the time lived in Sans Souci. Prior to working for the GIO I understand that he worked in country areas working for the local courts. Harry and Val had three children Wendy (as far as I know not married), Ian (deceased) married to Sandra and several children, and Roy (married to ? and several children). Harry was well known in NSW for being associated with the NSW Country Rugby Union Association and died recently at the age of 86. Val died many years ago from cancer and his son Ian died suddenly at home some years ago. I think Harry may have had a brother called John but I am not sure. This is the only information I have but I hope it helps you.
Regards
LINDA
