The 103-year-old from Springboig, in Glasgow, who is still volunteering, will receive the rarely presented Bar award, which goes to people who continue to demonstrate a high level of service over a significant period of time.
Margaret began helping the Women's Voluntary Service to collect goods for the wounded and the displaced in 1939 during the Second World War and is thought to be their longest serving recruit.
She also set up a club for stroke victims more than 35 years ago called The Lightburn WRVS Harmony Club and is a former Evening Times Community Champion and Scotswoman of the Year award winner.
Her only child, daughter Jean, 71, now does most of the work at the stroke cafe but Margaret still attends on every Monday she can.
She was awarded the BEM for her community work in 1989.
Modest Margaret said: "I don't really think I deserve it. I thought the first time it should have gone to the stroke patients. I got the benefit of seeing them getting a lot more confident."
Jean said: "It was such a shock. When we got the letter I thought there must be a mistake. I called Buckingham Palace and told them she already had the BEM. The lady came back and said it was right and she was one of only a few people to be awarded a second BEM.
"She's modest, she always has been."
Alison Love, Royal Volun-tary Service area manager for Glasgow and Lanark-shire, said: "Margaret has done a tremendous amount to help others over the years and despite her more than 70 years volunteering for the Royal Voluntary Serv-ice, her dedication and enthusiasm for volunteer-ing remains as strong as ever."
Patricia Cockburn, from Simshill, is also awarded a BEM for services to the community. Campaigning for her neighbours became a therapy after the sudden death of her only son, Scott, aged 36, from an epileptic seizure.
Patricia, who is chair-woman of Simshill and Old Cathcart Community Council, now campaigns on transport, environmental and anti-social behaviour issues.
Maria Righetti, from Glasgow, who set up the Parkinson's charity, Michael's Movers, is honoured for services to charity alongside Eric Flack for services to tennis and to the community in Drumchapel and Blairdardie.
Rosslyn Crocket, director of Nursing at NHS Greater Glasgow and Clyde is awarded with an MBE for services to nursing and midwifery.
She spearheaded a campaign launched two years ago to put the pride back into nursing.
Rosslyn said: "I am absolutely thrilled to accept this honour both personally and on behalf of nursing throughout NHS Greater Glasgow and Clyde. Nurses are now performing roles and duties that were once only carried out by doctors.
"However despite these great strides forward in our profession it is my view that we must never lose sight of the core principles of nursing - compassion, dignity and respect."

Glasgow 2014 chief execu-tive David Grevemberg, said: "On behalf of the team at Glasgow 2014, I am thrilled to offer our warmest congratulations.
"I can think of no one more fitting to receive this special honour. It is a great tribute to a great Glaswegian who continues to make an outstanding contribution to his home city and business and civic Scotland."
Glasgow lawyer Tasmina Ahmed-Sheikh, 43, is awarded an OBE for services to business and to Scotland's Asian community.
Mrs Ahmed-Sheikh is vice-chairwoman of W1 (Women First), a group set up to encourage women to share and exchange ideas about how best to achieve gender and ethnic equality in Scotland.
The SNP campaigner is bidding to become an MEP next year and is also a member of the pro-independence campaign Yes Scotland's advisory board.
She said: "It really is an honour to be recognised in this way. All of us like to be validated for the efforts we make and for me this is a validation of all the profile building that I and a host of others who support me have managed to achieve."
