Meaning & origin
Glennys is a Welsh feminine name that emerged in the early 20th century, first recorded in 1914. Its peak year was 1933, when it saw its highest usage. The name has since become rare, maintaining a stable trajectory without significant revival. Though not common today, Glennys retains a distinct Welsh heritage. Its top associated states are not recorded, suggesting its use was geographically diffuse.
Glennys is a Welsh feminine name derived from the word 'glan' meaning 'clean' or 'holy', but more commonly associated with 'glynn' meaning 'valley'. It is a 20th-century coinage, likely inspired by the male name Glenn or Welsh place names containing 'glen'. The name saw modest use in the early to mid-1900s, particularly in areas of Welsh settlement.
