Of all boys' first names in the United States, about 5.3 % begin with the letter C…
This makes the initial C 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 boys' first names. However, the average is only a median, as initials aren't completely evenly distributed, of course. Some letters are more commonly found as initials than others. Most boys' first names in the US start with the letters J and A, while the initials U and X are the least common.
In the USA, the most common boy’s first name with a C is currently Carter. Approximately 0.7 % of all newborn boys have been named Carter. Other popular boys’ first names with C are Christopher and Caleb. In the United States, the name Colby for boys is also found occasionally but is actually very rare.
