Overview
Marjorie Bruce or Marjorie de Brus (1316 or 1317) was the eldest daughter of Robert the Bruce, King of Scots, and the only child born of his first marriage with Isabella of Mar.
Marjorie's marriage to Walter, High Steward of Scotland, gave rise to the House of Stewart. Her son was the first Stewart monarch, King Robert II of Scotland.
Early life
Her mother, Isabella, was a noblewoman from the Clan Mar. Marjorie was named after her father's mother, Marjorie, Countess of Carrick. Soon after giving birth to Marjorie, at the age of 19, Isabella died. Marjorie's father was at that time the Earl of Carrick.
According to legend, Marjorie's parents had been very much in love, and Robert the Bruce did not remarry until 1302 (six years after his first wife's death), to a courtier named Elizabeth de Burgh.
