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. Benjamin Oliver Davis Sr. (1880 – November 26, 1970) was a United States Army officer.  He was the first African-American to rise to the rank of general in the U.S. military.

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): Mable Robinson Simms, (born March 29, 1914, Cape Charles, Virginia, died January 27, 2005, Boston, Massachusetts) was an African American jazz pianist and singer, she performed with notable jazz musicians, also as Mabel Robinson, in the 1940-50's, including Louis Jordan, Sammy Price, Skeets Tolbert, Sammy Davis Sr., Roy Haynes, Pearl Bailey, The 4 Blackamours, and released another album on her own.  She was born in Cape Charles, Virginia, raised in Norfolk and with her family, moved to Boston in 1931.  Her voice was signatory for being remarkably capable in both the jazz and blues arenas and she was a talented pianist.  This would land her guest singing roles with Sammy Price, Louis Jordan and Skeets Tolbert.
