Slaymaker (manufactured slays, which are weaving instruments. However, may also describe a person who manufactured wheeled carts, the oxen-driven variety formerly known as sleighs), resident of York, became a freeman in 1390. Name also spelled "Whyt".

Had a son of the same name who was also a "slaymaker" and "became a freeman" in 1394.

"Freedom of the city" in this context is connected to the medieval concept of "free status", when city and town charters drew a distinction between freemen and vassals of a feudal lord. As such, freemen actually pre-date 'boroughs'. Early freedom of the boroughs ceremonies had great importance in affirming that the recipient enjoyed privileges such as the right to trade and own property, and protection within the town.
