What is the meaning of the name Shionagh ?

The baby name Shionagh is a Female name , 3 syllables long and is pronounced shee-OH-nah (IPA: /ʃiˈoʊnə/).

Shionagh is Scottish Gaelic in Origin.

Shionagh is a Scottish Gaelic-derived feminine name, an anglicized rendering of Seonag, the diminutive of Seonaid (the Gaelic equivalent of Janet/Jean). Through this line it traces back to Latin Iohanna/Old French Jeanne and ultimately to the Hebrew Yohanan, meaning “God is gracious.” The spelling with “Shi-” reflects the Gaelic sh- sound in Seonag, while the -agh ending echoes the Gaelic diminutive -ag. Pronunciations vary regionally, often approximated as SHO-nah or SHO-nak.

Usage has been strongest in Gaelic-speaking communities of the Highlands and Islands, where Seonag and its anglicized forms appear in parish and census records from the 18th to 20th centuries. Today Shionagh is rare but recognizable in Scotland, sometimes chosen to honor Gaelic heritage. Close variants include Shonagh, Shona, Shiona, and Sheona; related Gaelic forms are Seonag and Seonaid, with broader cognates such as Sheena, Sìne (Jane), and Irish Siobhán.
