Are there databases for searching last names?

The Internet Surname Database and Behind the Name are databases for searching last names either by full specific name or the first letter of a surname. As of 2015, neither website requires any level of membership to take advantage of the databases.

The Internet Surname Database features an enormous search field that creates an easy-to-use interface. This is a family-run website reflecting 20 years of research, but despite this, some users may not find info on certain surnames. Behind the Name offers an etymology and history of surnames. Click on a letter at the homepage or type in a surname to obtain relevant details.
