Czechowski Name Meaning, Origin and Heraldry
Some records give Czech; others give Czechowski. Both point to the same Polish family name.
Census takers and immigration officers often wrote what they heard. The ending -owski in Czechowski marks a Polish derivative of Czech.
Heraldry is personal: arms associated with the Czech surname were borne by specific families, and sharing the name does not mean sharing the blazon. Research your Czechowski family history with a full surname report and painted coat of arms.
