I was given my name because …

My mother’s sister had had a daughter prior to my birth and she had used the name my mother had wanted to use for me, I became Jennifer instead of Jeanette.

From Nameberry: The name Jennifer is a girl’s name of Cornish origin meaning “white shadow, white wave”. Jennifer is the Cornish variation of Guinevere, which ultimately derived from the Welsh name Gwenhwyfar.
