Thelman is of Germanic origin, derived from the Old German elements 'theud' meaning 'people' and 'mann' signifying 'man'. It was introduced to England by way of Normandy following the Norman Conquest in 1066. The name gained popularity during medieval times but has since become quite rare. Notable bearers include Thelman Mathews, an English cricketer active in the late 19th century.
"Only seven babies named Thelman were born annually during the year 1922."
