Daynna is believed to have originated from the Welsh name Dyddgu, which means "bright." This unique moniker gained popularity during the late 1980s and early 1990s but has since become less common. It has a distinctive pronunciation, /deɪnə/, with emphasis on the first syllable. Daynna is often misspelled or mispronounced, but its true charm lies in its rarity and distinctiveness.
Daynna saw a total of 12 babies born with this name between the years 2003 and 2004, with 7 births occurring in 2003 and an additional 5 in 2004.
