Marion Gibbons (née Chesney; 10 June 1936 – 30/31 December 2019) was a Scottish writer of romance and mystery novels, whose career as a published author began in 1979.

She wrote numerous successful historical romance novels under a form of her maiden name, Marion Chesney, including the "Travelling Matchmaker" and "Daughters of Mannerling" series.

She also wrote romance novels under the pseudonyms Ann Fairfax, Jennie Tremaine, Helen Crampton, Charlotte Ward, and Sarah Chester.

Writing as Marion Chesney, her final endeavour was an Edwardian mystery series featuring Lady Rose Summer, a charming debutante with an independent streak, and Captain Harry Cathcart, an impoverished aristocrat.

[7][8] Little Brown, Chesney's publisher at the time of her death, announced that before the author became ill, she continued to write and was working on new material for her beloved characters, Hamish Macbeth and Agatha Raisin.
