Lyttleton was born on the family farm near Campbell Town, Tasmania, and brought up from 1879 in New Zealand on a sheep station at Rakaia in Canterbury.

She wrote initially under the name "Keron Hale", switching to "G B Lancaster" when her identity was revealed.

[1] She wrote about the formation of colonial identity and the legacy of imperialism in the lives of settlers and their descendants.

[1] Her first success was with The Law-Bringers (1913), which was made into a Hollywood feature film in the 1920s (as was The Altar Stairs).
