Boldt
A Germanic surname usually understood as coming from a byname for someone “bold” or brave.
The #7,344 most common surname in the United States (2010 Census) — about 1 in every 68,036 Americans shares it.
Etymology
Boldt is generally linked to the old Germanic word for “bold,” “brave,” or “daring.” The excerpts connect it with forms like Old English bald and German Bald/Bold, suggesting a nickname based on courage or a strong, forward character. In some cases it may also be related to older personal-name forms built on the same root rather than to a direct adjective nickname.
History
The surname is found in German and related North European naming traditions, and it appears in older surname dictionaries alongside forms such as Bald, Bolt, and Balz. In English records it is comparatively uncommon and may reflect later immigration from German-speaking areas. The family name has remained most strongly associated with German-language usage.
