This is from an online source, that has Jane Dickson Robertson's parents as Peter and Catherine, yet I see no Peter in the family:
"Robertson Jane Dickson 12 Jan 1838 Edinburgh, Midlothian Peter Robertson/Catherine Dickson James Curle Dunedin NZ 30 Mar 1860"
In Dunedin 1863 there is an Agnes Robertson, daughter of Peter Robertson of Edinburgh marrying at the house of James Curle:
