Margaret Beaufort was born in 1443, the only child of John Beaufort, 1st Duke of Somerset and Margaret Beauchamp.  At the age of 12, she was married to Edmund Tudor.  Despite her young age, Margaret quickly became pregnant and in 1457, she gave birth to her son Henry, who would later defeat Richard III at Bosworth Field and become king of England (Henry VII).  Margaret would marry two more times, live through the Wars of the Roses and see her grandson, Henry VIII, crowned as king.  She died in 1509, shortly after the death of her son.
