St. George appeared in
The Blue Bird (1911), and was best known in the title role in
Rebecca of Sunnybrook Farm, which she performed across the United States and Canada in a
Klaw and Erlanger production, 1911 and 1912. She was sixteen years old for much of the run of the show. "Miss St. George holds her audience in the delicious spell of her girlishness and ingenuous beauty," raved a Texas critic. She and her husband were art collectors, and had a particularly valuable collection of ancient Chinese artifacts. In 1927, Australian artist
James Peter Quinn painted her portrait. In 1972, she donated a pair of ancient Chinese bronze vessels to the
British Museum, with enough money to build a case for them. Other Cull collection items were auctioned by
Sotheby's in the 1960s, and she sold seven paintings by James Peter Quinn in 1975. Further objects from their collection were bequeathed to the British Museum in 1979. == Personal life ==
