About one in twentyfive girls' first names in the United States begins with the letter E…
This means that the initial E is neither particularly common nor particularly rare – with 26 letters in the alphabet, each initial occurs on average in 3.8 % of all girls' names. Reality is always different, of course: Some initials appear particularly frequently, while others are much rarer. The most common initials among girls' first names in the United States are A and S, while very few names begin with the letters U and X.
