In several cultures, people's names usually include one or more names in addition to the portion that is usually considered adequate to identify them.
 In a number of cultures where a given name is expected to precede the surname, such a name is likely to be placed after the given name and before the surname, and thus called a middle name.
 In English-speaking American culture, that term is often applied (arguably mistakenly) to names, occupying that position, even if the bearer would insist that that name is being mistakenly called a "middle name", and is actually (to mention several types of atypical cases):
Naomi Canning is a fictional character from the Australian soap opera "Neighbours", played by Morgana O'Reilly.
 Naomi was introduced as the daughter of established character Sheila Canning (Colette Mann), after producers decided they wanted to explore her background further.
 O'Reilly filmed her first audition in her garden in Sydney, before flying to Melbourne to audition in the studio.
 She competed with five other actresses for the part, but she believed that she was meant to get the role as Naomi is her middle name.
 A week after the second audition, O'Reilly's agent informed her that she had won the role.
 O'Reilly then relocated to Melbourne and began filming her first scenes in November 2013.
 She made her first screen appearance during the episode broadcast on 25 March 2014.
 The character departed on 2 October 2015, following O'Reilly's decision to pursue new acting roles.
Singh is a title, middle name or surname, which originated in India.
 Derived from the Sanskrit word for lion, it was adopted as a title by certain warrior castes in India.
 It was mandated by Guru Gobind Singh for all Sikhs.
 It was later adopted by several castes and communities.
 As a surname or a middle name, it is now found throughout the Indian subcontinent and among the Indian diaspora, cutting across communities and religious groups, becoming more of a title than a surname.
Latvian names, like in most European cultures, consist of two main elements: the given name ("vārds") followed by family name ("uzvārds").
 During the Soviet occupation (1940 - 1991) the practice of giving a middle name was discouraged, but since the restoration of Independence Latvian legislation again allows giving of up to two given names and it has become more common to give a middle name to children.
