The three weird sisters (oftentimes referred to as the three witches) are the first characters to appear on stage.
The real king Macbeth's wife's name was Gruoch (you can see why Shakespeare didn't use it). It was her second marriage; by her first to Gillecomlan she had a son, Lulach, who succeeded Macbeth as king.
The name of Macbeth's thandom is Cawdor.
There is no mention of her fathers name only A sleeping Duncan's resemblance to him which prevents her from killing the Scottish king herself.
Brave Macbeth
Globe theatre
Macduff's first name is not mentioned in Shakespeare's play "Macbeth." He is simply referred to as Macduff throughout the play.
In Act 1, Scene 2 of Macbeth, the captain refers to Macbeth as "brave Macbeth" in line 16. This title emphasizes Macbeth's courage and prowess in battle.
When Macbeth refers to Macduff he is talking about a man who holds the title Thane of Fife.
King Duncan
The pronoun "it" in the conversation between Macbeth and Banquo likely refers to the witches' prophecy about Macbeth becoming king.
The first apparition warned Macbeth, 'Macbeth, Macbeth, Macbeth: beware Macduff, Beware the Thane of Fife. Dismiss me. Enough'
The name Macbeth first was used in Act 1 Scene 1 of the Shakespearean play 'Macbeth'. The three witches were gathered together on the open heath. They were deciding where their next meeting would be. The second witch settled on the heath. The third witch explained that the heath was where they all would be able to meet with Macbeth [Line 7].
