Brunson is a surname of English origin, derived from the Middle English word 'bronsun', which means 'brown-haired'. It is believed to have been given as a nickname to someone with brown hair. The name became popular in Scotland during the 14th century and has since spread throughout the world.
The name Brunson experienced a notable resurgence in popularity from 1973 onwards, with the number of births nearly doubling compared to previous decades. However, it appears that this trend did not continue into recent years, as the birth count in 2010 was equal to that of 1973.
