Peggy is born in Maryland (possibly Baltimore), United States of America. One source from January of 1949 notes her age as 25.
1943, June 17
Peggy (as "Interlude") appears in the Broadway musical Early to Bed.
1944, May 13
The Brooklyn Daily Eagle announces that Peggy has been cast as Venus in the Broadway musical Helen Goes to Troy.
1944, April 6
Photographer and one day actor/writer Julius "Skippy" Adelman photographs Peggy in her Venus costume.
1944, April 24
Helen Goes to Troy opens with Peggy as Venus. I presume she had left the cast of Early to Bed prior to this engagement.
A photo of Peggy dressed as a lion tamer appears in Esquire Magazine.
1944, May 13
Early to Bed closes. (As Helen Goes to Troy is already running, I presume Peggy had left the cast of ETB sometime earlier.)

Peggy appears as Venus in LIFE Magazine.
1944, June 23
Peggy, in her Venus costume, appears in Yank, The Army Weekly.
1944, July 2
The photo of Peggy as Venus that appeared in the June 23, 1944 issue of Yank is also published in the British Edition of Yank, The Army Weekly.
1944, July 7
The Daily News (New York) notes that, in addition to Helen Goes to Troy cast member Donald Buka ("Orestes") leaving the production, Peggy is "getting ready to make her debut as a singer." Is one to assume this means that she will be leaving the show to pursue a singing career? HGTT would close the week after this announcement so it seems possible that she was simply on to the next thing.
1944, July 15
Helen Goes to Troy closes. It is assumed that Peggy is still playing the role of Venus as the show closes. Piers Beer ads that were running as late as August, 1944, still feature her so my guess is that she never left the show.
1944, September 20
It is announced in The Daily News (New York) that Peggy will have a feature role in Felix Brentano's Mr. Strauss Goes to Boston.
1945, May 4
Peggy Corday ("the singer") is quoted in the Iowa City Press Citizen saying of José Melis' performance at New York's Le Ruban Bleu, "For him I'd wear bobby sox." (Syndicated article from the New York Post) Was Peggy performing at Le Ruban Bleu or just in attendance?
Peggy appears on the cover of Picture-Wise magazine.
1946, July 15
Peggy opens Burlesque at the Boston Summer Theater, Boston. Burt Lahr stars and Ann Corio choreographs. The Billboard magazine gives it a positive review in their July 27, 1946, issue but does not mention Peggy.
1947, December 16 (likely date)
The television program Photographic Horizons debuts on WABD, New York. Peggy is a model for the photographers.
1948, May 2
Peggy possibly appeared on the Theater Guild television program in The Great Catherine. This is absolutely unconfirmed. However, her interview with Radio and Television Best (March, 1949) references Peggy doing "television shows, including a Theater Guild production with Gertrude Lawrence." The book Postwar Television Drama, 1946-1949 references a May 2nd, 1948, Theater Guild broadcast from Studio 8G of The Great Catherine staring Gertrude Lawrence. According to a syndicated column in the April 22nd, 1948, Austin American-Statesman (Texas), et al, the broadcast was to be recorded so that a copy could be sent to George Bernard Shaw.
Peggy opens Lysistrata at the Westport Playhouse, Connecticut.
1949, January (presumed date)

Peggy is named Miss Television of 1949 by Radio and Television Best magazine.
1949, March 1

1949, July 2
