Carl
Carl comes from the Germanic "karl," meaning free man — the same root as Charles. The name was originally a description of a free (non-serf) man in Germanic society. Carl the Great (Charlemagne, 742-814) was the founder of the Carolingian Empire. The name has been continuously used in Germanic-speaking countries for over a thousand years. Carl was a top-50 American name from 1890 to 1960, peaking at #19 in 1915. Carl Jung (1875-1961), the Swiss psychiatrist who founded analytical psychology, is one of the most influential thinkers of the 20th century. Carl Sagan (1934-1996), the astronomer whose "Cosmos" (1980) popularized science for a generation, gave the name a scientific dimension. I find Carl has a brisk, slightly Germanic quality — the single syllable is direct, and the "C" opening is firm. The name has been outside the US top 500 since 2017.
