Helen Aldrich was born in
Rochester, New York, on October 29, 1818. She was the daughter of Obed and Melintha Hart (Potter) Aldrich, and was the oldest in a family of twelve children. She was a seventh-generation descendant of the
Quaker George Aldrich, who came to the United States in 1630. Early in her life, her father, Obed, lost a great deal of money by "endorsing for a friend". De Kroyft attended
Westfield Academy in 1832–36, and
Genesee Wesleyan Seminary (now
Syracuse University) in
Lima, New York in 1837–43, where she was a valedictorian. In 1834, at age 15, she came up with a plan regarding how to pay for her higher education. She alternated between teaching school in the winter and attending school in the summer, ultimately graduating from the university. ==Career==
