How would the story be different if kit was a boy in reality.

I'm not sure what you mean.... in actuality, Kit could be a boy in the period.... the events could have happened. This isn't likely, but it is possible. The novel is historical fiction, meaning, the story is based on certain realities.

What I mean is when Tom Boyd was going to Cumberland with Pete and Kit, how would it be different if kit was a boy. If kit was a boy in the first place, would the story be different
