The family named ARNOLD derived from ARNULF (eagle-ruler) a Germanic-Scandinavian name was brought to England by tribes who invaded several times her history. The first were the Angles, Jutes, and Saxons who invaded England when Rome fell. Rome's protective grip on England, failed in the year 383, when Magnus Maximus withdrew the last Roman legion from England to the Rhine. But in 406, the Rhine River froze--for the first time in twenty years-- and the barbarians under Alaric succeeded in crossing in Gaul.
 
In 410 Emperor Honorious sent word to England that Rome could not any longer defend either herself or her provinces. That very year Alaric and his brother Arnulf sacked and burned Rome, and marched unhindered through the very center of the western empire. During the next thirty years England did her best to defend her eastern and southern coasts from the barbarians. But with no Roman army to prevent an invasion the Angles, Jutes, and Saxons soon conquered most of Roman Britain.
