Sioban is a feminine name of Irish origin. It appears to be a variant spelling of the more common 'Siobhan,' which derives from the Norman French name 'Jeanne,' the feminine form of 'John,' ultimately meaning 'God is gracious.' The unique spelling of Sioban maintains the same pronunciation as Siobhan (approximately 'shi-VAWN'), but offers a slightly simplified spelling. This variant is quite rare compared to the standard Siobhan, which became popular outside of Ireland during the mid-20th century. As with many Irish names, its pronunciation may not be immediately intuitive to non-Irish speakers, which might contribute to its relative obscurity in international contexts.
