One Buddhist legend presents Nang Kwak as Nang Supawadee (or Subhavadi) of a Brahmin trading family that converted to Buddhism.Ara Wilson (2008), The Sacred Geography of Bangkok’s Markets, International Journal of Urban and Regional Research, Volume 32.3, September 2008, page 635 According to this legend, in the small town of Michikasandhanakara, in the Indian province of Sawadtii, there was a married family, Sujidtaprahma and his wife Sumanta, who had a daughter named Supawadee. They were merchants who sold small amounts of wares on the markets, only earning just enough to maintain their small family from day to day. One day, they were discussing their hopes and dreams for the future, and decided that they should try to expand their business to make more profit and begin to think of being able to save something for their old age.
