Mercia is a female first name.
Recently, the name Mercia 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 girl in 100,000 has been named Mercia. That means that a girl named Mercia is exceptional and may not meet another person with the same name her whole life.
Well, you might say, you probably figured that out yourself! But what you might not know is: The letter M is a quite popular first letter for girls' names. That’s because 8.5% of all common girls’ names in the US begin with this letter. Only the first letters A and S are more common for girls' names.
With six letters, the name Mercia is of average length. In fact, 28% of all common first names in the US consist of exactly six letters. 24% of all first names are shorter, while 48% have seven 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.
Therefore: As 8.5% of all girls' names start with an M, this initial letter occurs nearly 2.5-times as often as all 26 letters on average – and the most common one of all the girls’ names starting with M is Mary.
If your name is Mercia 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...
So that everyone really understands you when you have to spell the name Mercia, you can simply say:

These flags are used for maritime communication - each flag represents a letter.
In the navy, sailors of two ships might wave flags to each other to send messages. A sailor holds two flags in specific positions to represent different letters.
In Morse code, letters and other characters are represented only by a series of short and long tones. For example, a short tone followed by a long tone stands for the letter A. Mercia sounds like this:
