Meaning & Origin

Glynnis peaked during the Baby Boom, when 40 babies received this name in a single year (1964). That era was defined by classic, post-war American naming, and Glynnis has a more concentrated history, reflecting a specific cultural moment rather than a broad generational wave.

Glynnis is not in the current top 1,000 girl names nationally, making it an uncommon choice — though your state or community may differ.

Glynnis is a girl's baby name of Welsh origin, a feminine form of Glyn or Glenn, from the Welsh glyn meaning 'valley' or 'glen.' The -nis ending gives it a more distinctly feminine form than the simpler Glynn or Glyn.

Glynnis carries the musical lilt characteristic of Welsh names — the double consonant and soft vowels create a name that sounds as if it was made to be sung. Welsh actress Glynnis Johns, known for her role in Mary Poppins (1964), brought the name gentle international recognition.
