Madelyn Ann McDonald was the sister of Mary Eugenia McDonald. Mary Eugenia married Arthur Murosky, Marian Elaine Murosky's older brother. Both families lived in Erie, Erie County, Pennsylvania and the members of the extended families became close. The Murosky family was living at 638 East 23rd Street when the postcard was sent. The McDonald family lived a few blocks away at 422 East 19th Street in the early 1940's.
Madelyn would been 13 years old when she sent this postcard to Marian age 10. Madelyn was most likely traveling to visit her McDonald family members which included her grandparents and cousins that lived in Pittsburgh, Pennsylvania.
