It is now “Siofra”. It’s Irish/Gaelic:
“The modern Irish girl’s name, Siofra, means an elvish or changeling child, deriving from Síobhra(í) meaning fairy(/fairies). The Aos sí, siabhra (commonly anglicised as “sheevra”), may be prone to evil and mischief. However, the Ulster folk song ‘The Gartan Mother’s Lullaby’ also uses “sheevra” simply to mean “spirit” or “fairy”.”
Changeling Ireland/ Siofra Name for the stories/lore behind Changelings & their relationship with fairies in Ireland. Also the meaning of the modern name Siofra.
I resonate with this for a couple of reasons from when I was younger
