Janet started as a pet form of Jane, but has long been used independently. Five hundred years ago Janet was a royal favorite in Scotland, where it remains a popular choice. Here, however, Janet has been on a downhill slide since the 1960s, with Grandma Janet now knitting booties for baby Janae. Or even, increasingly, Jane.
There have been several Janets recently involved in US government, Janet is a leading member of the Jackson family, and Janet Evanovich is a bestselling author; and in the past there have been first Best Actress Oscar winner Gaynor, Psycho screamer Janet Leigh, and the mother of Jackie Kennedy.
There are several attractive foreign versions that might prove appealing alternate namesakes for Gran Jan--Gianetta, Zaneta, Janneth, Sinead or Janica.
