Only about every fortieth first name in the USA begins with the letter G…
This means that the initial G is represented below average: According to this, each letter (given 26 letters in the alphabet) would appear as an initial in about 3.8 % of all names. However, 3.8 % is just the average. Of course, the initials of first names aren’t that evenly distributed, with some letters being rarer than others. In the US, the initials A and J are particularly frequent for first names, while very few names begin with the letters U and X.
In the US, the most common girls’ name with G is Grace, and the most popular boys’ name with the initial G is Gabriel. Nearly 0.5% of all newborn boys in the United States have been named Gabriel recently, while only 0.4% of newborn girls have been named Grace. Other popular first names with a G include Gabriella, Gianna, Grayson, and Gavin.
