Etymology
Tomaszewski is a Polish surname formed from the personal name Tomasz, the Polish form of Thomas, with the place-name suffix -ew-/-ewski that often signals origin or association. In practice, it usually meant “someone from Tomaszew” or “of the family/place associated with Tomasz.” The deeper root of Thomas goes back through Greek and Aramaic to the Hebrew name Ta’oma, meaning “twin.”
History
Surnames in -ski became especially common among Polish families tied to estates, villages, or landholding names, and later spread more widely across Polish society. Tomaszewski would originally have identified a person from a settlement called Tomaszew or a related lineage linked to the given name Tomasz. The surname is common in Poland and also appears in diaspora communities in North America and elsewhere.

Fun fact
The ending -ski is one reason many Polish surnames sound place-based, but it can also blur the line between a true locational surname and one formed from a first name.
