Jersain is a male first name.
Recently, the name Jersain has been given only a handful of times a year and is therefore particularly rare, at least in the US. In recent years, not even one boy in 100,000 has been named Jersain. That means that a boy named Jersain is exceptional and may not meet another person with the same name his whole life.
Well, you might say, you probably figured that out yourself! But what you might not know is: The letter J is the most popular first letter for boys’ names. 10.1% of all common boys’ names in the US start with this letter. The second most common first letter in boys’ names is A.
With seven letters, the name Jersain has a typical length for first names in the US. In fact, 26% of all common first names consist of exactly seven letters. 52% of all first names are shorter, while 22% have eight letters or more. On average, first names in the US (not counting hyphenated names) are 6.5 letters long. There are no significant differences between boys' and girls' names.
That means that if 10.1% of all boys’ names start with a J, this initial letter occurs nearly three times as often as all other letters on average. And, by the way, of all the boys’ names that begin with the letter J, the name James is the most common.
If your name is Jersain and someone asks after your name, you can of course just tell them what it is. But sometimes that isn't so easy - what if it's too loud, and you don't understand them well? Or what if the other person is so far away that you can see them but not hear them? In these situations, you can communicate your name in so many other ways: you call spell it, sign it, or even use a flag to wave it...
