History
The roots of Jerrold began in the pre-7th-century, of German and French origin. See the top page for more details. However, the name Jerrold is a name more commonly connected with the Dark Ages. The name and variations of Jerrold were first put on record in 1230 for a man named John Gerard in the small village of Pipe Rolls in the county of Somerset, England. The name's popularity started in the late 11th century and reached its peak in the mid-12th century, under the rule of Henry III because of its biblical and violent sense. Other early Jerrold's include: 
Henry Jerard of Essex, England, 1284
Burkhart Gerhart of Heilbronn, Germany, 1293 
Since then, its given name has had reasonable popularity and its surname has been uncommon.
