Siobhan
Siobhán (English pronunciation: shi-VAWN; Irish pronunciation: [ˈʃɪwaːn̪ˠ] or [ʃəˈvˠaːn̪ˠ]) is a feminine Irish name.
It is derived from the Anglo-Norman Jehane and Jehanne (Modern French Jeanne) which were introduced into Ireland by the Anglo-Normans in the Middle Ages. The name is thus a cognate of the English Joan, and ultimately derived from the Latin Ioanna and Iohanna (modern English Joanna, Joanne), which are in turn from the Greek Iōanna. This Greek name is a feminine form of the Greek Iōannēs, which is in turn a shortened form of the Hebrew Johanan (יוֹחָנָן Yôḥānān, a shortened form of יְהוֹחָנָן Yəhôḥānān), meaning 'God is gracious', and origin of the masculine name John and its cognates.
