A more thorough explanation:

SWEIN

Swein (also spelled swain) is a historical term used to describe a forest freeholder.

An example of a swein would be a person who owned land in a forest and had the right to hunt and gather resources from it.

Another example would be a person who had the responsibility of maintaining the forest and ensuring its sustainability.

These examples illustrate how a swein was a person who had a special relationship with the forest and was responsible for its management and preservation.
