I received the following information from Australia 25 years ago which may be of interest to you.
Samuel Brooks Gange - born 15 Feb 1877 Devon, England
son of Henry Gange and Susan, nee Brooks.
Samuel Brooks and his father were both builders.
Samuel married Alice Aenkerson, youngest daughter of Sydney Aenkerson, builder, of London.
The names Henry Gange and Aenkerson look as if they may be your family.
