Are these photos of my great-aunt, Dora Lillie Mahler? My mother said that some of them were "Dora, friend of Grandma," also known as "Madcap Dora" because she was what was once called a "stitch." But my mother may not have known that her mother-in-law Henrietta Mahler Burk had a younger sister named Dora, who died in June, 1950.
Above, Dora seems to be in a traditional folk costume of Eastern Europe. Below, she's with a beau (apparently she never married). The bottom photo is probably the oldest--check out that teeny, tiny waist!
