She is the daughter of actress, performance artist, and model Tilda Swinton and Scottish playwright, artist, and designer John Byrne. She is related to American actress Alexa Swinton.
Her father was born in Paisley, Renfrewshire, Scotland, and likely had Irish ancestry. The Swinton family is an ancient Anglo-Scots family that can trace its lineage to the Middle Ages. They are said to be one of three British Isles families that can trace their unbroken land ownership and lineage to before the Norman Conquest.
Honor’s maternal grandfather was Major-General Sir John Swinton (the son of Alan Henry Campbell Swinton and Marie/Mariora Beatrice Evelyn Rochfort Alers-Hankey). Sir John was born in St. George Hanover Square, London, England, and had Scottish, English, and Northern Irish ancestry. Honor’s great-grandfather Alan was born in Chelsea, London, England, the son of George Sitwell Campbell Swinton, a politician, herald, and officer-of-arms, who was born in Edinburgh, Midlothian, Scotland, and whose own father was author and politician Archibald Campbell Swinton; and of Elizabeth “Elsie” Ebsworth, who was born in Russia, to an English father and a Scottish mother. Honor’s great-grandmother Marie was born in Westhampnett, Sussex, England, the daughter of Cecil George Herbert Alers-Hankey and Gertrude Clare Fetherstonhaugh.
Honor’s maternal grandmother was Judith Balfour, Lady Swinton (née Killen, the daughter of Harold Charles Killen and Marion Spottiswood Balfour). Lady Swinton was born in Merribee, Barellan, New South Wales, Australia, and was of Northern Irish, Scottish, and English ancestry. Harold was born in Prahran, Victoria, Australia, the son of William Wilson Killen, whose parents were Irish, his mother from Donegal; and of Marion/Marian Young, whose parents were also from Ireland, from Antrim and Down, respectively. Honor’s great-grandmother Marion was born in Hoiles Cottages, Colinton, Edinburgh, Scotland. Her father, Andrew Francis Balfour, was born in Edinburgh, Scotland, and was a Captain in the Royal Navy; his own father was John Hutton Balfour, a prominent botanist and professor of botany, who was President of the Berwickshire Naturalists Club.
