First names with O

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.

In the US, Oliver is currently the number 1 most popular boys’ name to start with an O, while Olivia is the most popular girls’ name. In second and third place are names such as Olive, Ophelia, Owen and Oscar. Far rarer names starting with O in the US are Opal or Otto.
