Schwannberger
Schwannberger is a surname of German origin. The name is believed to be a habitational surname, possibly derived from a place name that is no longer easily identifiable or has changed over time. Such surnames often indicate ancestral origins from a specific town, village, or geographical feature. The "Schwann" element could relate to a swan, a common motif in German folklore and heraldry, while "berger" typically means "mountain" or "dweller of the mountain." Therefore, a literal interpretation might suggest someone associated with a "swan mountain" or a person who lived near such a feature.
Like many European surnames, Schwannberger likely became established as families migrated and settled in different regions.
