Hulda.

First attested in the 1800's. Exact origin uncertain. A Nordic female given name, probably either formed from huld (“friendly, gracious”), from Old Norse hollr (“faithful, loyal, gracious”), or derived from hulda (“secrecy, hiding; something hidden”). The latter is probably related to hylja (“to cover, hide”), from Proto-Germanic *huljaną (“to cover, veil”), ultimately from Proto-Indo-European *ḱel- (“to cover, hide”). The adjectival explanation ultimately goes back through Proto-Germanic *hulþaz (“inclined, favourable; gracious, loyal”) to a homonymous Proto-Indo-European root *ḱel- (“to lean, incline, bend”). Compare Danish Hulda, Swedish Hulda, Icelandic Hulda and Faroese Hulda (“female given names”).

Ultimately from Biblical Hebrew חֻלְדָּה (“Huldah”), the name of the biblical prophetess mentioned in 2 Kings 22:14–20 and 2 Chronicles 34:22–28. The Biblical Hebrew name is traditionally analysed as a feminine formation related to חֹלֶד (“weasel; small burrowing animal”), from the root ח־ל־ד, associated with digging or burrowing. The precise animal denoted by the Biblical Hebrew word is uncertain and has variously been identified as a weasel, marten or mole-like animal; hence the name is conventionally interpreted as “weasel”. An alternative etymology connects the name with חֶלֶד (“life span, duration of life”), so its original literal meaning is not entirely certain. The name appears as Ancient Greek Ὀλδά (Oldá) in the Septuagint and as Latin Holda in the Vulgate. Martin Luther's German Bible uses Hulda, the form subsequently widespread in Germanic biblical tradition.
