What is the meaning of the name Sionagh ?

The baby name Sionagh is a Female name , 3 syllables long and is pronounced shee-OH-nah.

Sionagh is Irish (Gaelic), Scottish in Origin.

Sionagh is a Scottish Gaelic feminine given name, essentially the diminutive Seonag/Sionag with the suffix -ag(h), and widely anglicized as Shonagh or Shona (pronounced roughly SHO-nah/SHON-ə). It belongs to the Gaelic family of names equivalent to Jane/Joan, descending through Scots and Latin Iohanna from Hebrew Yochanan, “God is gracious.” The spelling Sionagh reflects Gaelic orthography and should not be confused with Irish sionnach “fox,” which is unrelated.

Use is well attested in Highland and Island parish registers from the 18th to 20th centuries, and it has seen periodic revival alongside modern Gaelic cultural movements and within the Scottish diaspora. Close variants and relatives include Seonag, Sionag, Seonaid (Janet), Sìne and its diminutive Sìneag; anglicized forms include Shonagh, Shona, Sheona, and Shiona. Broader cognates include Irish Siobhán, plus Jane, Jean, Joan, and Janet. Across all forms, the core meaning remains “God is gracious.”
