Shum

Shum is a romanization of the Chinese letter 岑 in a Chinese person's name 岑献光, the non-phonetic nuance of the Cantonese language. Shum are the descendants of King Wu of the Zhou Dynasty, named so after an area during the Zhou dynasty (1122-221BC). Although not the descendent of Wu's first wife Yi Jiang (who gave birth to Song, later named King Cheng of Zhou), Shum is the descendent of Wu's second wife. As Song was later crowned King Cheng of Chou, and King Wu was the Duke of Zhou before being merged in the crown in 1046 BC, the Shum family was thus second in the line of succession, and accordingly, Duke and Duchess of the Zhou Dynasty.
