In Act 2 Scene 3, the murdered corpse of King Duncan I [d. August 14, 1040] was discovered by Macduff. Those who were present at Inverness Castle reacted in different ways to the shocking news. For example, the King's sons, the future Kings Malcolm III [d. November 13, 1093] and Donald III [d. 1099], were suspicious of the circumstances of the crime and feared similar violent repercussions on themselves as the sovereign's sons and heirs apparent. They chose to flee. Donalbain, who became King Donald III, escaped to Ireland. Malcolm relocated to England.
Macbeth is first 'Thane of Glamis' then he is bestowed the title 'Thane of Cawdor' then king of Scotland
It's a two-part answer. One, Macbeth is a traitor and killed the King of Scotland. Macduff is loyal to the rightful heir, Malcolm. Macduff assists Malcolm in the retaking of Dunsinane castle and murders Macbeth. But Macbeth also hired assassins to have Macduffs family murdered. Macduff's wife and children were all murdered after he fled to England with Malcolm.
The 11th century. Macbeth was King of Scotland from 1040-1057.
Scotland
King Duncan had two sons: Malcolm and Donalbain. After fleeing Duncan's murder, Donalbain fled to Ireland, and Malcolm fled to England. Malcolm later led the attack on Dunsinane and took the throne after Macbeth was killed.
The son of a king who fled to Ireland in the play Macbeth is Malcolm, the son of King Duncan. Malcolm escapes to Ireland to gather support and allies to overthrow Macbeth and regain the throne of Scotland.
Because he was the one who left them in the first place. He didn't leave Scotland with the intention of ditching them, he just fled Scotland to escape the imminent wrath of Macbeth (and to persuade Malcolm to overthrow Macbeth); not realizing Macbeth would kill his wife and children too.

Macbeth's two great feats were his successful defense of Scotland against Norwegian invaders and his victory over the traitorous Macdonwald in battle. Additionally, he later becomes King of Scotland after Duncan's murder.
Macbeth lives in Scotland.
At the beginning of the play "Macbeth," Duncan is the king of Scotland. He is a benevolent and respected monarch.
Duncan's sons, Malcolm and Donalbain, fear for their safety after their father's murder and suspect that they may be the next targets. They believe that staying in Scotland would put their lives at risk, so they decide to flee to England and Ireland respectively to seek help and gather support to eventually overthrow Macbeth.
In this scene Lennox talks about how Macduff has fled to England. There are no "Scottish noblemen from England"--they are from Scotland, and that is why they are Scottish. Macduff is, however, a Scottish nobleman in England, and there are soon to be many others. Shortly, as well, Siward and Northumberland are going to be English noblemen in Scotland, since they will accompany Malcolm's invasion.
