Okay kiddo, let me explain who Baron Keith was.
Imagine you have a group of friends who like to play games or sports together. They might have a leader, or someone who is really good at the game, that they all listen to and respect.
That's kind of like Baron Keith. He was a really important person who would help make decisions about big problems or disagreements in a country called Scotland a long time ago.
He was like the "head referee" or "the boss" when people needed to figure out what to do about something. People would go to him when they needed help with things like making new laws or settling fights between different groups of people.
So, Baron Keith was an important person who helped make decisions and solve problems in Scotland a long time ago.
