Germanic names in Italy started to proliferate after the fall of the Roman Empire due to the Barbarian Invasions of 4th-6th centuries.
Over time, there was a growing mismatch between the ethnicity and the naming, similar to the Gaul.
While initially Gothic names belonged to the Goths, by the 10th century the choice was influenced by the fashion independently of the ethnicity.
Often the names were hybrids: German suffixes were added to Roman roots (e.g., Forteramnus =Forte + -ramn + -us) and vice versa (Hrodemia, from Hroðr).
[6] Christianity has played a considerable role in preservation of the classical Greco-Latin names, related to religious ideas and saints.
