Wyllys is a unique and historical given name of English origin, derived from the Old English word 'wil' meaning 'will' or 'desire', combined with 'leah' signifying 'wood' or 'clearing'. It was first recorded as a forename in the 13th century. Over time, Wyllys has evolved and been associated with notable figures such as Governor Thomas Wyllys of Connecticut Colony during the mid-17th century.
"The name Wyllys was given to 10 newborns over five years, with an even split of 5 births each in 1915 and 1920."
