Allyn is an uncommon, yet distinctive female given name of Welsh origin. It is derived from the ancient Welsh personal name 'Alaw,' which means 'harmony' or 'peace.' Allyn gained popularity in the late 19th century but remains relatively rare today, perhaps due to its unique sound and spelling. It is often associated with the Welsh legend of the Lady of the Lake, who played a significant role in Arthurian mythology. The name Allyn might appeal to those seeking a distinctive yet meaningful name for their child.
The name Allyn experienced significant fluctuations in popularity over the past century, with notable peaks and troughs. Its most popular years were 1946 and 1950, with 27 and 65 births respectively. However, it declined substantially after the 1950s, with fewer than 30 births per year from 1954 onwards, except for a few spikes in the late 1980s and early 1990s. Since 2000, Allyn has been used rarely, with only double-digit figures in four years (2006, 2008, 2009, and 2011). The most recent data shows a continued decline, with single-digit births per year since 2015.
