Most knights went through training, and the training was usually only given to the sons of noble families, such as men with titles of nobility or knights. In theory, a king or certain other members of nobility could knight a person for whatever reason he might have. There were many cases of this happening, usually as a reward for some deed.

These women were all, or nearly all, untrained women and not members of the nobility, but they were all legally knights.
