Mary Ann Lawrenson (née Molyneux; 23 March 1850 – 1 January 1943) was an English activist in the co-operative movement and an educationalist.
[1] In 1876 she married John Marcus Lawrenson a government clerk and fellow co-operator, with whom she had a son.
[1] In 1885 Lawrenson succeeded Acland as general secretary of the Guild, working across the country to support the establishment of local branches during a period of rapid growth.
However, following her husband's death in the First World War, she ceased being active in the co-operative movement, though she was honoured as part of the Guild's 50th anniversary celebrations in 1933.
She later moved to Brighton where she died on 1 January 1943 (aged 92) following an extended period of poor health.
