Meaning and origin of Sian
Sian is a Welsh and Hebrew name that means “Welsh form of Jane, God is gracious”.
Sian is the Welsh name Siân, a form of Jane or Jeanne, which go back to the Hebrew Yochanan, God is gracious. In Welsh the Si- spelling stands for a sh sound, so Siân is said SHAHN. It has long been a common girl's name in Wales, and English speakers outside Wales sometimes read it as see-AHN. In the US it is used for both boys and girls. Siân, with the accent, is the Welsh spelling. The name is short, Celtic in feel, and closely tied to Welsh identity.
