People interested in looking up the origin of a name can use websites such as Behind the Name and Baby Name Wizard. These sites cover names from around the world and include Biblical, Medieval and mythological names. Names can be searched using characteristics such as gender, first letter or meaning.
Behind The Name provides information on the meaning and history of a name, as well as variants in other languages. For example, a search for the name Elizabeth shows that it is derived from a Hebrew name meaning "God is my oath."
The Baby Name Wizard is maintained by Laura Wattenberg, author of the book "The Baby Name Wizard." The website includes name meanings and also incorporates her research into name trends. It has features such as popularity graphs and suggestions for names for sibling sets.
