geralding on Family Tree Circles

I have information about the Stanton family who emigrated to Nelson, New Zealand, in 1842 on the Clifford,also John William Theodore Lechner, who arrived circa 1848, also in Nelson.

I am also trying to find out thet truth of a family story that John Hindmarsh was appointed to be Harbour master at Calcutta as a reward for his help as a merchant seaman in the Napoeonic wars. There is a vivid description of his Indian wife watching him, from the balcony of his home, being drowned by a crocodile in the Ganges, when a boat carrying him and others capsized and he was thrown out.The others got back in but he was taken before they could reach him. A finger with his ring on it was found a few days later. This story sounds pretty fanciful, but there must be some truth somewhere - I haven't had any luck online even finding out if he really was the harbour master, or whethe he had issue. On-line references are usually to a more famous John Hindmarsh who was the first governor of Adelaid and had a distinguished career.
