A name derived from medieval times originating in germany. It literally means "strong one" and was given to those who are morally, socially, mentally, and physically strong. They can withstand anything, and are known to be highly admired amongst friends and other people alike. Many Dieffenbachs are also notorious for their ability to communicate precisely, and heal others using their communication abilities, hence the definition of being socially strong.
