Jollie is of English origin, derived from the Middle English word 'jolye', which means 'merry' or 'joyful'. It was used as a nickname for someone who was cheerful and lighthearted. In some cases, it may have also been used as a diminutive form of the name Julie or other similar names ending in '-lie'. The name Jollie is quite rare today, but it adds a unique touch to those who choose to bear it.
"Jollie is quite uncommon, with only five girls named so each in 1930 and 1945, totaling just ten births over these two decades."
