I am not a descendant of Janet but her father (John Hutton Waugh) and my gggrandmother (Catherine Waugh/McKenzie) were brother and sister. I have names of Janet and John's children and some of their descendants. However I have never met any them nor have I completed that part of my tree. Those "other related names" are direct descendants although I do not have the youngest ones name. My guess is your photo is pre 17/8/1927 when Janet's mother died or pre 29/6/1928 when her father died.
It would be great to get it to a family member.
From another forum I know you are in Tauranga. I am in Auckland. Perhaps between us we can achieve this.
