Rhyannon is an uncommon, gender-neutral given name of Welsh origin, derived from the combination of 'Rhy' meaning 'flowing' and 'Ann' meaning 'grace'. This unique moniker has been growing in popularity since the late 20th century, with a gentle cadence that rolls off the tongue, making it both distinctive and melodic. Spelling variations include Rhiannon, Ryannon, and Rhianna, though each retains the same Welsh roots and meaning.
"Rhyannon saw a peak in births in 2005 with eight babies, while the years 1996, 1999, 2004, and 2007 to 2011 had five or fewer births each. Over these six years, there were a total of thirty-six Rhyannon babies."
