Mrs Rachel Quinlan Marshall, who has died at the age of 78, was the widow of businessman David Marshall.
They met while both were students at Halifax Technical College in the early 1950s.
Born in Bradford but brought up in Halifax, Mrs Marshall was the daughter of Arthur Leslie Kitchen, an engineer who was a partner in the firm Kitchen and Wade.
Her middle name Quinlan was derived from a family connection on her mother’s side.
After her marriage in 1955, Mrs Marshall lived first in Southowram and later in Shibden.
Her husband – who served as a Brighouse councillor and as president of the Brighouse and Rastrick Band - co-founded the Halifax Tool Company and later became chairman of Marshalls, the Southowram-based quarrying and building products company that had been founded by his great grandfather in the 1880s.
For many years, Mrs Marshall was a member of the Salvation Army in Halifax, playing a highly active role in its charitable and social programmes.
In later life her travels took her to countries such as Iceland and she paid two visits to the Falkland Islands.
Her husband died in 2000 and her daughter Isobel in 2002. Mrs Marshall is survived by three sons and six grandchildren.
Her funeral takes place on Monday, July 23, at the Salvation Army Citadel in Halifax, with interment at St Anne’s Church, Southowram.
