Margaret Anne Sinclair, PCC (29 March 1900 – 24 November 1925), religious name Mary Francis of the Five Wounds, was a Scottish Catholic nun of the Colettine Poor Clares.

Born on 29 March 1900, at nine in the evening, in the two roomed flat beneath the ground floor, at 24 Middle Arthur Place, Edinburgh.

[1] In 1922, seeking a life of solitude and prayer, Margaret applied to join the Poor Clares in Notting Hill, London.

The two would say goodbyes; Andrew was emigrating to Canada while Margaret would enter the convent of the Colettine Poor Clares in Notting Hill.

Many members of the religious community doubted Sinclair's ability to live a cloistered life owing to her humble heritage.

[2][3]Margaret contracted laryngeal tuberculosis and was admitted to a sanatorium run by the Sisters of Charity at Warley, Essex, on 9 April 1925, where she remained until her death on 24 November that same year,[3] and was buried at Kensal Green in north west London.

[1] On 6 February 1978, 100 years after Scotland's Roman Catholic hierarchy was restored Margaret Sinclair was declared venerable by Pope Paul VI.
