Siobhán is a unique, beautiful Irish female given name, derived from the Old Irish 'Scíathach,' meaning 'of the fairy mound.' It was traditionally used to describe strong, courageous women, often warriors, in ancient Celtic mythology. In modern times, Siobhán has become more widely recognized internationally due to its association with notable figures such as Irish writer and Nobel laureate Seamus Heaney's sister, Siobhán Heaney. The name is pronounced 'Shvee-awn,' with the emphasis on the second syllable.
"The name Siobhain peaked in popularity during the early 1990s with six births each recorded in 1990 and again in 1994."
