The Peggy Stewart was a Maryland cargo vessel burned on October 19 1774 in Annapolis as a punishment for contravening the boycott on tea imports which had been imposed in retaliation for the British treatment of the people of Boston following the Boston Tea Party. This event became known as the "Annapolis Tea Party".

Peggy Stewart, real name Margaret O'Rourke, (5 June 1923-) was an American film actress who starred mostly in B-movies during the 1930's and 1940's. Her sister, Patricia O'Rourke, was an Olympic swimmer, and was married to World War II hero and well known B-movie actor Wayne Morris.

Stewart's career began when she was cast in the 1936 film Wells Fargo, alongside Joel McCrea. By the early 1940's she was on contract with Republic Pictures, starring regularly with Allan Lane, Sunset Carson, and Bill Elliott. During that time she played in several episodes of Adventures of Red Ryder. She usually played the part of the tough heroine, rather than a passive girl needing to be saved. Along that time she married western actor Don Barry. From 1944 to 1951 she starred in thirty five films, most of which were serials and westerns. She also starred with Gene Autry several times during that period as well as appearing on at least one episode of "The Cisco Kid", titled "Oil Land" which first aired on 10-10-1950.

In 1949 she played alongside Jim Bannon in Ride, Ryder, Ride. She again played the part of heroine to Bannon in 1950, starring in The Fighting Redhead. In 1952 she starred with Bill Elliott in Kansas Territory.

Her career slowed in the 1960's, and by the 1970's she was residing in Studio City, California. Semi-retired, Stewart still continued to act on occasion, and played a bit role on one episode of Seinfeld in 1990 titled "The Implant". In that episode she played the part of the aunt to George Costanza's temporary girlfriend.

Florida-born Peggy O'Rourke's parents divorced when she was very young. Peggy's mother eventually married a wealthy attorney named Stewart, and Peggy took his name. She grew up in Atlanta (where she developed the athletic skills she would later demonstrate in her many westerns for Republic). On a family vacation to Los Angeles to visit her grandmother, Peggy, as a lark, attended classes at a dramatic school, but the acting bug hit her hard and when it was time to return to Atlanta, Peggy talked her mother into letting her staying with her grandmother. As luck would have it, a resident of the apartment building they lived in was character actor 'Henry O'Neill', who took a liking to Peggy and got her cast in her first film, Wells Fargo (1937). She picked up a few more small roles, and acquitted herself so well the parts started getting bigger and she was working more often. She married actor 'Don 'Red' Barry' in 1940, and was eventually signed by Republic Pictures, Barry's studio, to make westerns and serials. In three years, Peggy did almost 30 films at Republic, most of them westerns. She appeared in two of the studio's more successful serials, but when Republic assigned her to another one, she protested. She didn't particularly like working in serials, preferring the feature westerns, which didn't take as long to film. Eventually the struggle with Republic got to the point where Peggy asked for her release, and she got it. Although she wanted to start doing films other than westerns, she had made so many at Republic that she found herself basically unable to find work in any other genre. She freelanced for Monogram, Allied Artists, PRC and other small studios until she was picked up by Columbia--which immediately put her into serials. She eventually decided to leave the film business, and did so in 1953. She did do some television work (mostly westerns!) while raising her family, and also performed in the Los Angeles theatrical community. She kept her hand in the film business, making occasional appearances in some lower-budget westerns, made-for-TV movies and inexpensive horror pictures.
