Only about 1.4 % of first names in the United States begin with the letter O…
This means that the initial O is found much less frequently than average. On average, each letter appears as an initial in about 3.8 % of all names, considering the 26-letter English alphabet. The distribution of initial letters is undoubtedly uneven – after all, some letters occur much more frequently, while others are much less frequent. In the US, the most common initials of first names are A and J, while the letters U and X, on the other hand, are initials for very few names.
