This category is for surnames that are derived from patronyms. For example, the modern English Johnson is derived from a patronym, and no longer is used to show the name of the bearer's father. True patronyms, like the Icelandic Jónsson, should not be included in this category.

This is a set category. It should only contain pages that are Patronymic surnames or lists of Patronymic surnames, as well as subcategories containing those things (themselves set categories). Topics about Patronymic surnames in general should be placed in relevant topic categories.
