This snippet of information may or may not be related but I find it interesting how Dequetteville Terrace (Adelaide) was named and the connection to a Mrs Robin.
Dequetteville Terrace The name appears as "Dequeteville" on a plan of the subdivision of Kent Town lodged in the General Registry Office (no. 226 of 1854) by the subdividers, Henry Ayers and James Robin. The latter was born in Guernsey, Channel Isles in 1817 and his mother was a daughter of Rev John de Quetteville, the first Wesleyan Minister in the Channel Isles. See The Christian and Methodist Journal, 10 August 1894, page 4a (copy in Mortlock Library), Observer, 28 July 1894, page 30b, Chronicle, 11 August 1894, page 8a. An obituary of Mrs James Robin is in the Observer, 10 August 1907, page 40c.
