Here are some that I found:
Violet, Doris, Enid, Iris, Ethel, Mavis, Esther, Ada, Agnes, Ivy, Glenda, Edith, Nora, Nellie, Rose, Olive, Pearl, Emily, Greta, Gretchen, Martha, Dora, Alice.
Clive, Alec, Colin, Cecil, Herbert, Hubert, Quentin, Warren, Norbert, Alf, Sid, Edgar, Ted, Winston, Frederick, Benedict, Frank, Malcolm, Darren, Eugene, Wilfred.
Yes, its interesting how some 'retro' names have become more populur (Violet, Rose, Emily, Quentin, Frederick) whereas others have not (yet?).
