Middle name: 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):

Latvian name: Latvian names, like in most European cultures, consist of two main elements: the given name ("vārds") followed by family name ("uzvārds").

Jeff Strabone: Jeff Strabone is a Brooklyn-based American scholar, political activist and civic leader.  In 2016, his website "directelection.org" listed the names and addresses of members of the U.S. Electoral College, and he urged people to write to electors to ask them not to vote for president-elect Donald Trump, an effort which brought him national attention.

He has been a leader of Brooklyn's Cobble Hill Association, a neighborhood preservation group.  He is the co-founder and chairman of the New Brooklyn Theatre.  In 2008, he changed his middle name to "Hussein" as a show of solidarity with then presidential candidate Barack Obama, who was running for the office of president, and who had been criticized for his Muslim-sounding middle name.  He is an associate professor of English and teaches British and African literature, and he was granted tenure at Connecticut College in 2016.  He commented about the post-election effort:
