The name "Blahynia" is a East Slavic male name derived from the adjective "blah" (meaning "good" or "peaceful") with the suffix "-ynia." This name was first mentioned in 1202, and a bearer of this name was Blahynia, a voivode of the Hungarian King Andrew II. In 1204, it is also recorded by M. Moropykin, along with other names such as Dobryn, Dovhyn, Sviatyn, and Sukhin. It is worth noting that there is also a South Serb female name "Blahynia," which comes from the root "blah-" with the addition of the suffix "-ynia."
