The name Catheryn, pronounced 'KAY-th-rin', is of Welsh origin and means 'pure'. It is a variant spelling of Catherine, which itself comes from the Greek 'Aikaterine', meaning 'pure'. The name has been popular throughout history due to its association with early Christian saints such as Saint Catherine of Alexandria. In literature, it is famously borne by Catheryn Hunter, the heroine of Sir Walter Scott's novel 'The Fair Maid of Perth'.
The name Cathern experienced significant fluctuations in popularity over the years, with a notable spike in usage from 1913 to 1927, reaching its peak in 1922 with 27 births. However, it appears that this popularity declined sharply thereafter, as evidenced by fewer than 10 births per year from 1935 onwards, and even fewer than 5 births annually since the late 1960s. The total number of births with the name Cathern over these years is 1080.
