About one in twentyfive boys' 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 boys' names. Reality is always different, of course: Some initials appear particularly frequently, while others are much rarer. The most common initials among boys' first names in the United States are J and A, while very few names begin with the letters U and X.
