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.
