The surname Cohn is a traditional Jewish family name whose roots lie in the Hebrew word Kohen, meaning priest.

It is traditionally associated with the descendants of the biblical Aaron, the brother of Moses, who served as the first high priest of the Israelites. The name therefore indicates a hereditary priestly lineage within the Jewish community.

In many regions of Europe the name took the form Kohn, an Anglicised spelling that also emerged from the German word Kohn for priest. Other common orthographic variants include Kohen, Cone, and Kahn, all of which are used by families of Jewish origin.

Some bearers of the name are not descendants of the Aaronic priesthood. In the Russian Empire several families adopted the surname Cohen in order to avoid compulsory military service; in that society the priestly caste was exempt from conscription.

Another set of surnames that are occasionally transformed into Cohn are the Gaelic Irish toponyms O Cadhain of Connacht and O Comhdhain of Ulster. In these cases the prefix O indicates “male descendant of”, and the personal bynames relate to “wild goose” and a shared gift, respectively. Anglicised forms such as Cowen, Coen, and Coyne also exist.

Historically the Cohns exercised specific religious duties. During the Second Temple period, from about 516 BC to 70 AD, those bearing the name performed sacrifices, blessings and adjudicated religious matters within the Temple in Jerusalem, as well as maintaining the Tabernacle and other holy sites.

Following the destruction of the Second Temple and the subsequent diaspora, families taking the surname dispersed throughout the world. Registers from the Mambro Synagogue in London record births of Cohns as far back as 1772, and further records show the name appearing in County Mayo, Ireland, in the mid‑nineteenth century.

Today the surname is common across many Jewish populations worldwide, especially in the United States, Germany, Israel and the United Kingdom. The name remains a marker of Jewish identity, although it no longer guarantees priestly status or religious observance.

Across the diaspora a wide spectrum of spellings has arisen due to regional pronunciation and orthographic practices. In addition to the variants listed above, forms such as Cahan, Kahane, Coen, Cowan, Koln and Hacohen are found, reflecting the linguistic diversity of Jewish communities.

Thus, the surname Cohn remains a historically significant marker of Jewish heritage, signifying a possible connection to the ancient priestly caste of Aaron, while also representing the varied pathways through which Jewish families have adopted and adapted the name across centuries and continents.
