Beltz
A surname of uncertain origin, probably linked to a nickname or dialect word rather than a single well-known place or trade.
The #7,246 most common surname in the United States (2010 Census) — about 1 in every 67,075 Americans shares it.
Etymology
The available historical excerpts do not give a direct etymology for Beltz. In English and German contexts, the form may reflect a surname built from a nickname or an older dialect word, and the spelling with -tz can also suggest Germanic influence. Because the evidence here is indirect, the safest conclusion is that Beltz is a surname of uncertain derivation rather than one with a firmly established meaning.
History
The surname is found in English-language sources by the 19th century, and the cited Burke excerpt shows it as an established family name in Britain. Modern bearers are concentrated in the United States, which likely reflects later migration and spelling stabilization. No single famous origin point can be confirmed from the excerpts provided.

Fun fact
