Corbyn is a name of Cornish origin, derived from an old family name meaning 'crow'. It was historically popular in Cornwall and other parts of southwest England, but has since become more widespread. The name Corbyn first gained notable attention in the 21st century when it was chosen by British politician Jeremy Corbyn for his son in 2003.
"The name Corbyn experienced a notable increase in popularity between 2011 and 2017, with the highest number of births recorded in 2017 (31) and 2022 (26). However, the name has shown considerable fluctuation throughout the years, with some years seeing fewer than 5 births."
