Orkney, Scottland is mentioned for the first time in The Flight of Gemma Hardy when we learn that Mrs. Marsden grew up there (Livesey 13). According to Scotland Info Travelguide, Orkney is an island in northern Scotland that consists of much smaller islands (SIT). The islands are separated regarding proximity to the largest island which is known as "the Mainland" while other islands, though have names, are mainly associated with being North or South of the Mainland (SIT). Ockney is an island with deep, rich history dating back to the Vikings in 3500 BC.
