This name was most notably borne by Domald of Sidraga (c. 1160-1243), a powerful Dalmatian nobleman and feudal lord who for several years was Prince of the city of Split, which was (and is) located in what is nowadays Croatia. Since not much is known about his personal life (such as the family that he was born into, which thus casts some doubt on his ethnicity), we cannot say anything for certain about the meaning and origin of his given name.
If we assume that he was an ethnic Slav (the chances of which are high), then his given name is most likely of Slavic origin also. Its first element is then almost certainly derived from Slavic domu
meaning "home, house" (see Domagoj
). The second element of his name is much less certain, but it seems that there is a chance that through metathesis, it might be derived from Slavic vladeti
meaning "to rule" (see Vsevolod
) or even Slavic mladu
meaning "young" (see Mladen
But if Domald was not an ethnic Slav, he might have been a Dalmatian Italian instead, in which case it seems likely that his name is of Germanic origin. After all, in his day, Italians were well familiar with Germanic given names, thanks to the influence of the Ostrogoths, the Lombards and the Franks a few centuries prior. His name should then be a variant of Domuald
, which is the ancient Germanic cognate of the Old Norse name Dómaldr
. It could even be a hybrid Latin-Germanic name, as these existed in Italy as early as the 8th century AD. The name should then consist of Latin dominus
meaning "master, ruler, lord" (ultimately from either Latin domus
"house" or Latin domo
"to tame") and of Germanic wald
meaning "power, rule".
All in all, it is clear that at least in the case of the aforementioned Dalmatian nobleman, there are multiple possibilities for the etymology of the name Domald. But until we find out more about his personal life, none of them can ever truly be ruled out and should thus be kept in mind.
