It was perfectly normal to have no middle name. um... well.... Sir Isaac Newton didn't have a middle name. im serious. belive me. i knew that for 3 years already becasue we learned about him 3 years ago. i studied alot about him. <br /><br />[edit to improve]: During his time period, many people didn't have middle names, and some only had initials, such as Harry S. Truman.
My family name is Newton, and it is the same family name that my father has and that my grandfather and his direct male ancestors had. The family name is also called the last name, because most countries in Europe write it last: in Philip Newton, the Philip comes first and the Newton comes last.
