Malcolm (Duncan's son) did not kill Macbeth, it was Macduff (Thane of Fife).
sidney is his daughter, but need to know son's name
The oldest son of Duncan is Malcolm. He is next in line for the throne after his father Duncan, but he faces challenges in doing so from Macbeth in the play "Macbeth" by William Shakespeare.
MacBeth then Banquo's son Malcom.
Malcom is Duncan's son. Macbeth kills Duncan (king of Scotland), but not Malcom; Malcom flees to escape suspicion of his involvement in his father's murder. He later returns to Scotland, where, after Macduff kills Macbeth, he is crowned king. Hope this helps!
At the end of Shakespeare's play Macbeth; Malcolm, son of Duncan is proclaimed to be King of Scots. (In actual history, Macbeth was succeeded by his son Lulach; who was then was assassinated and deposed by Malcolm)
Malcom X's Daughter Were is more info on this young lady?
"The Prince of Cumberland! That is a step on which I must fall down or else o'erleap." The idea was that the Prince of Cumberland was the heir apparent, like the Prince of Wales in England.
Malcolm Canmore, later king of Scotland, was the son of King Duncan. Also Donald Ban was his son, and he also became king later on. Both of these appear in Shakespeare's play.
As in England calling your son the Prince of Wales marks him as the heir apparent, Duncan's calling Malcolm the Prince of Cumberland marked him as the next king. This would certainly be "a step on which [Macbeth] must fall down, or else o'erleap."
