The short answer
Jennifer is an English feminine name derived from Cornish Gweniver and Middle Cornish Gwynnever, which are cognate with the Welsh name Gwenhwyfar and etymologically parallel to Guinevere. The name was traditionally confined to Cornwall before gaining wider prominence in the early twentieth century following George Bernard Shaw's 1906 play The Doctor's Dilemma. By the late 1930s, Jennifer began ascending in the United States, ultimately becoming the most popular name for girls in America between 1970 and 1984. It remains an enduring choice with Celtic roots.
Meaning and etymology
Jennifer represents the English development of Cornish Gweniver, stemming from Middle Cornish Gwynnever and Proto-Brythonic *Gwɨnnohuɨβar. It is an etymological doublet of Guinevere and cognate with Welsh Gwenhwyfar (derived from Celtic roots gwyn and hwyfar). The initial consonant /d͡ʒ/ developed under Anglo-Norman phonological influence.
