In November 1837, Strangways, Young Bingham Hutchinson, and a party explored the Fleurieu Peninsula and Lake Alexandrina region, searching for other outlets to the Southern Ocean.
Giles E. Strangways, (an associate of John Finnis and Charles Sturt in their pioneering cattle drive of 1838), was his younger brother.
Strangways was a member of the South Australian Legislative Council and Colonial Secretary from 22 August 1837 to 12 July 1838.
[5] His widow, an invalid, went to live with Henry Strangways, then with Mrs. B Clark at Childers Street, North Adelaide in an arrangement which has the appearance of protective custody.
As a result, Mrs Strangways was taken in Rounsevell's carriage to Mr Fowler's home "Elderslie" at Woodside,[6] where she died some eighteen years later.
