Rollyn is of Scandinavian origin, derived from the Old Norse name Rǫgnvaldr, which translates to 'powerful' or 'famous'. It is composed of two elements: 'róðr', meaning 'rowing', and 'valdr', signifying 'ruler' or 'leader'. This unique name gained popularity during the Viking Age but has since become quite rare. In its modern form, Rollyn is often associated with Scandinavian culture and heritage.
"Rollyn was a popular baby name between 1925 and 1969, with peaks in the late '20s to early '30s and again in the mid-1950s."
