Jearld is of Old English origin, derived from the word 'eorl', meaning 'nobleman'. It was a popular given name among the Anglo-Saxons during the Middle Ages. The name Jearld fell out of fashion following the Norman Conquest in 1066, but it has seen a resurgence in recent years.
"Jearld saw its peak popularity between 1937 and 1950, with over 26 births in 1937 and a high of 19 births in 1950. However, it has been quite uncommon since the late 1950s, with most years seeing fewer than 10 births."
