The name "Dobrokh" is likely a truncated-suffix formation with the suffix -ok from the two-root name Dobroslav. This name appears in Latin-script records of the 15th-16th centuries in the Upper Tisza basin. For example, in 1417, the names of serfs Dobroch, Kosza, and Zobonya were recorded in the Szatmár county (Mak Sza 224); in 1583, a serf named Dobrach was mentioned in the village of Turterebesh in the Ugocsa county (Szabó 258). In Polish territories, the name Dobroch was first mentioned in 1493.
