What about Barbara? Victoria Coren-Mitchell and David Mitchell have a little girl called this, apparently. I'm not far off 60 and that was already rather an old-fashioned name when I was young, so maybe it's time for it to return.
Classmates of mine included Amanda, Sally, Clare/Claire, Janet, Charlotte, Rebecca, Sharon, Tracy, Karen, Sarah, Judith, Julie, Julia, Rosalind, Rosemary, Victoria, Nicola, Jane, Jayne, Suzanne, Gillian, Jill, Ruth, Fiona, Catherine, Kathryn, Kate, Anita, Barbara, Caroline, Carolyn, Tanya, Lindsay, Margaret, Elizabeth, Alison. A lot of those are quite rare now.
Boys' names were less varied, I think.
