Charles has been a popular name for boys in the U.S. for over a century. It was in the top 10 boy names from the late 1800s until the mid 1950s, dropping to No. 11 in 1955. 1 The name dipped in popularity in the second half of the twentieth century, but even at its lowest point (No. 63 in 2010) it was still one of the top 100 boy names in America.
