What is Jr.?

Jr. indicates that a person is named after his father. In the olden days when there was a high child mortality rate, there was a tradition of naming the child. It was very common to name the son after his father in the hope that he would follow in the footsteps of his father and would do good things. There is no rule enshrined by law that which child should be given the title of Jr. It completely depends upon the family or an individual who wants to take Jr. There are some of the rules unofficially followed while naming a child Jr.

It includes that a father should be a living person if the son is called a Jr. Or it may also happen that Sr. (Senior) must have died. Then only it can take up Jr. Or when Jr. child has got married. Usually, it is expected that Jr. is named after the father. He should be alive. Sometimes after repeating the same name for generations, it does not matter whether the original Sr. is a father or any other male relative.

What is ii? 

Everybody wants that his or her child will just be like his father or a respected member of the family. Naming the children ‘the second’ is done to remember the eldest or the dearest member and to pay respect to him. Mostly it was done for the Kings and Queens. We can find in history numerous examples when there were named as ii. Like Henry II, Edward II, etc. Usually, it is used when a child is named after other members like his uncle, grandfather, maternal grandfather, nephew etc.

ii suffixes were mostly used for the rulers so that it can be easy to memorise and write the names in the royal family trees. A child can also be named as ‘the second’ by his mother if his father has died before his birth. It can be seen in girls and women too. However, in the modern era, its usage is very rare. In previous times, it was prevalent in England.
