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.
Isaac Newton was born in Woolsthorpe, England on January 4, 1643. His father, a farmer who was also named Isaac Newton, had died three months before his birth. His mother remarried when Isaac was three years old and left young Isaac in the care of his grandparents.
