Sianna is a unique and captivating female given name of Welsh origin, derived from the ancient Celtic word 'sian', meaning 'star'. It is pronounced /ʃɑːnə/. This name gained popularity in the late 20th century, particularly in English-speaking countries like Wales, England, Australia, and Canada. Sianna's usage peaked in the early 2000s but has since maintained a steady presence among modern baby names.
"Sianna saw a significant rise in popularity from the mid-90s onwards, peaking around the early 2000s with over 70 births per year consistently until 2005. However, it has since declined, with fewer than 60 births annually since 2014."
