The god of death, Yamarāja, is said to have born as a Shudra (partial incarnation), popularly known as Vidura in the Mahabharata, due to a curse from Mandavya Rishi.
Most of the incarnation of the divinities I came across are either from Brahmin womb or Kshatriya womb, with the only exception of Vidura, known to me at least, or I can't recall any more at the moment.
Are there any other incarnations of divinities (gods, goddess, devas-devis, rishis, and other celestial beings), described in the Sanskrit scriptures preferably, that incarnated from a Vaishya or a Shudra or a Chandala womb?
Mostly interested in any kind of divinity being born off a Shudra womb.
