I’m a sixties baby. One of my classes had four Janes and four Carolines and three Joannas. Otherwise there were a couple of Claires plus the scattering of Gillian, Hazel, Heather, Tracey, Helen, Claire, PatricIa (Trish not Pat), Elizabeth (Beth not Lizzy), Libby, Sharon and a couple of Karens. Always a good scattering of Marys but often as middle names. Claire was very common as the second part of a hyphenated first name, just as when my DC were in primary ever second girl was “something-Louise”.
Ten years above me would have been the Janets, lots of Susans and Margarets, Lynne, Brenda, Barbara, Belinda, Deirdre, Janet, Linda, Hilary. Plus the Marys as middle names or first names where middle name was the daily use name.
I’m of the view that if Ethel can be in Vogue for celebs any name can return.
