Almost every twentieth girl's first name in the USA begins with the letter D…
This makes the initial D a great deal more common than average: As there's 26 letters in the alphabet, each letter appears as an initial in about 3.8 % of all girls' first names. In fact, the letters that form initials aren’t distributed evenly – some initials are very common, while others are very rare. The most common initials among girls' names in the United States are A and S, while very few names begin with the letters U and X.
In the US, the most common girl’s name with the initial D is Delilah. Recently in the United States, approximately one in 500 girls has been named Delilah. Other well-known names with a D are Daisy and Destiny. The name Dorothy, on the other hand, is also well known in the US and has been used occasionally in recent years, but is generally still quite rare.
