The name "
Dats" is attested in the monuments of Ukrainian writing only from the 16th century. For example, records show names like Dacz Olexicz and Dacz Pachuticz. In the 17th and 18th centuries, patronymics formed from the name
Dats, such as Chwedecz Daczevich and Datsenko
Petro - a resident of the village of
Bila Tserkva. In 1649, five Zaporozhian Cossacks were recorded under the name
Dats.Today, the name
Dats is still used in the southern part of Tyachivshchyna (Zakarpattia) as a colloquial equivalent of the official name Andriy. Compared to other languages, in Bulgarian there are names such as Daca, Daco, and Dace, in Croatian - Daca, Daco, and in Old Polish - Dadz.Regarding the etymology of the name, opinions vary. Most likely, it is a truncated-suffixed formation of a calendar name starting with "Da-", similar to Danilo, Darius, or Dasiy, or it may be a result of the distortion of names that contain the sound "d," such as
Bohdan or Yordan. Another version suggests that it is a truncated variant of the Old Slavic or Old Polish two-root name Daczbogius, recorded in 1482. The East Slavic and Ukrainian equivalent is the anthroponym or theonym
Dazhboh or Daiboh. A possible intermediate stage to the variant name
Dats could be the record Dadzbog or the voiced Daczbog, as in a record from 1414 in the village of Dobriany. It can also be compared with the Polish personal name Dadzko from the 13th century. The idea of the origin of the name Dadzko through a truncated-suffixed formation from the two-root Polish name Dadzibog, meaning
Dazhboh, is also supported by researchers.
