Siubhan is a feminine name of Irish Gaelic origin, representing an alternative spelling of Siobhán, which is the Irish equivalent of Joan or Jane. The name ultimately derives from the Norman French 'Jehanne,' which comes from the Hebrew name Yochanan, meaning 'God is gracious.' This variation maintains the traditional Irish pronunciation (approximately 'shiv-AWN') while offering a spelling that some may find more intuitive in certain regions. Like its more common counterpart Siobhán, this name celebrates Irish cultural heritage and carries a sense of timeless elegance. Siubhan remains relatively rare, even compared to Siobhán, making it an uncommon choice that still connects to established naming traditions. The name peaked in popularity during the mid-20th century Irish cultural revival but has remained relatively uncommon.
