Family Theme Naming

Sometimes, authors give their characters related names. While Theme Naming adds a sense of unity or cohesiveness to the work, it doesn't always make much sense in-universe. Family Theme Naming is when the names of related characters follow a pattern or fall into a category. Somewhere along the line, a character would have had to make the decision to name his or her children something that resulted in Theme Naming. This could result in similarly named siblings or span the entire family tree.

A subtrope of Theme Naming. Theme Twin Naming is a subtrope. See also Alliterative Family.
