The ancient Ukrainian name Dancha, and over time the surname Dancha, like other anthroponyms with the suffix -cha(t), primarily functioned among Ukrainians in the Carpathian region. For example, among the sons of the Sinevir serf Fedynych in 1726 were: Dancha, Mykhailo, Petro, and Toma. In the Maramureș village of Birsana in 1584, the nobleman Jo. Danczya was recorded. Additionally, in 1592, the nobleman Ge. Danchi from the village of Uglia was documented; in 1605, the serf Dancza Griga from the village of Kolochava; and in 1618, the serf Fr. Danczi from the village of Bystria.The name Dancha is formed using the diminutive suffix -cha(t) from the personal name Dan, which in the Carpathians is associated both with the genetically Slavic name Bohdan and with calendar names like Danilo and Yordan. This name also shares common roots with Serbian names Dancha, Danche, and Danchо.
