Margaret Boyle was born in the Battersea district of southwest London, and grew up in London's Irish community. Her father was a fiddle player from the Donegal Gaeltacht, and her mother a dancer. In addition to her father, her other main tutor was Oliver Mulligan, a singer from County Monaghan, resident in London. As a youngster Boyle joined the Fulham branch of Comhaltas Ceoltóirí Éireann, through which she won All‑Britain singing competitions. As a teenager Boyle performed with her brothers Kevin and Paul as The Boyle Family. Through the overlapping folk club and Irish music scenes in London she met Steve Tilston, a professional folk singer, and they married in 1984.
In 1984, at the recommendation of Mike Taylor of the musical group Incantation, Boyle joined the live performance production company of Christopher Bruce's ballet Sergeant Early's Dream. Six musicians performed English, Irish and American folk songs at the back of the stage, while a dancer interpreted them at the front. Boyle toured the world with the company for several years. The 1994 CD version of the production featured Incantation plus the Sergeant Early Band, including Maggie Boyle and Steve Tilston.
In 1992, Boyle formed the harmony group Grace Notes with Helen Hockenhull and Lynda Hardcastle. The trio enjoyed success in concerts and festivals throughout the country, and were particular favourites at the annual Whitby folk week. They made five albums, starting with Down Falls the Day (1993) and ending with 20 (2012), to celebrate Grace Notes’s 20th anniversary.
In 2012, Boyle began a website-based travelogue-style project to capture performances and collaborations with various folk songwriters she admired. Entitled Kitchen Songs, it includes performances and duets with Ralph McTell, Jez Lowe, Pete Coe and Steve Tilston – all recorded in their respective kitchens when she visited their homes. Also in 2012, Boyle released a solo album, Won't You Come Away, on Wild Goose Records with Paul Downes on guitar, mandocello and mandolin and Jon Boden on fiddle. She is mother to Joe Tilston, guitarist of the band Random Hand. Much of the Boyle family continue to make music today, including Boyle's brother Kevin, who released his second CD since Bon Cabbage, to which Maggie Boyle contributed, in 2009. Kevin Boyle also continues to tour and record with his band, Le Cheile.
