Surname

A surname is a name added on to the given name of individuals, often to indicate a family or clan relationship.

Vulcan family names are nearly unpronounceable by Humans. 

Kzinti surnames were titles added to their names over their careers. 

Most Klingons were addressed by their given names, and their full names had a patronymical surname, such as "son of Mogh" or "daughter of W'mar". 

The Trill are born with family last names. Once joined, they adapt their host's name as their surname. 

Many Bajorans, who have their family names as first names, have "distorted" their names in order to more easily acclimate to Starfleet and Federation norms. 

Members of Vilix'pran's species are addressed by the second part of their name. For example, Vilix'pran is addressed as "Pran." 

The Miradorn, seem to have a surname as a hyphenated part of their own name. Evidence of this is Ah-Kel and Ro-Kel. 

Charles Tucker referred to Feezal as "Mrs. Phlox," likely confusing Human custom with Denobulan customs. 

The Ferengi do not appear to use surnames, although they have occassionally been heard to use "son of..." or "daughter of..." in a similar fashion to the Klingons.
