If possible I am trying to find out what happened to Joan and Robert.
Beryle Leonore Cochrane mother was Elizabeth Kate Carr. Elizabeth had a sister sarah jane carr and a half brother Edmund Perry.
When their parents died in 1878, the three children were sent to the Industrial schools. The parents were Samuel Carr(Parkhurst Exile on Equestrian 3) and sarah Jane hilliard died geelong 1878 from exposure.
As far as i can tell robert and Joan are the descendants of Samuel Carr
