Andrew was the son of Sir Norman de Leslie.
He obtained via his wife's dower the baronies of Rothes and Ballinbreich.
In 1305, Andrew was ordered by King Edward I of England, after rebelling with William Wallace to stay out of Scotland for six months.
He gained charters for his service from King Robert I of Scotland and signed the Declaration of Arbroath in 1320.
Andrew died before 1324, as his wife obtained papal dispensation in 1324 to marry Sir David Lindsay of Crawford.
