"Baby" Ruth Cleveland

https://en.wikipedia.org/wiki/Ruth_Cleveland

"Baby" Ruth Cleveland was the first child of United States President Grover Cleveland and the First Lady Frances Cleveland. Her birth between Cleveland's two terms of office caused a national sensation. However she was a very sick child who died at the age of twelve of diphtheria, and was buried in Princeton Cemetery.

The Curtiss Candy Company claimed to have named the "Baby Ruth" candy bar after her, 17 years after her death, something Snopes.com denies. It further seems unlikely to have truly been named after Ruth Cleveland as the candy bar was renamed "Baby Ruth" in 1920 while Babe Ruth was nearing the top of his popularity, in the middle of his career. The candy bar was formerly known as Kandy Kake from 1900 - 1920.
