Louise Hearst Entzminger lost her class ring in a central Florida swimming hole in the 1930s.
Scuba diver Reed Banjanin found the Mississippi Women's College ring last summer and was determined to find its owner.
The Orlando Sentinel (http://thesent.nl/y8t8Rn ) reports 38-year-old Banjanin used the Internet to track information about Entzminger. He learned she died in 1975, but was able to find her grandson John Entzminger in Oakton, Va.
John Entzminger turned 75 the day Banjanin called about his grandmother's ring. It arrived via mail on Christmas Eve.
The retired engineer suspects his grandmother lost the ring while visiting relatives in Seminole County in the 1930s. He plans to pass it along to his grandchildren as a family heirloom.
