Davidsz

Davidsz is a Dutch-language patronymic surname meaning "son of David." The ending -sz is a historical spelling variant of the Dutch suffix -zoon, used in early modern Netherlands and Flemish-speaking regions to form patronymics. The name would have identified an individual as the child of a man named David; over time, such patronymics could become fixed surnames or simply appear in signatures in archival documents.

In historical records, Davidsz appears most often in the 16th to 18th centuries in the Low Countries, including parish, civil, and notarial sources. The spelling is characteristic of Dutch orthography from that era, and modern usage often shows the same name as Davidsz in reproductions of older documents, but more commonly as Davids or Davidszoon in other records. The modern distribution of Davidsz is limited, and it is considered relatively uncommon as a current surname outside genealogical contexts.

Variants and related forms include Davids, Davidszoon, Davidse, and Davidsson in related linguistic areas; spelling may vary by region and historical period. Davidsz can also appear as a component of longer compound surnames in some archival entries.
