Mary was born in New Vienna in 1885. Her grandfather, John Hoskins, was born in the New Vienna area in 1813 after the family migrated from North Carolina in the early 1800s. According to the Wilmington College Alumni News of May 1950, page 2, she retired from Wilmington College in 1950 after serving as associate professor of education for 25 years, having taught more than 2000 prospective teachers. She had a "total of 46 years of teaching experience, teaching in the intermediate grades at Martinsville for three years, the primary grades at New Vienna for 11 years, and in the old Clinton County normal school for five years before joining the Wilmington College faculty."
In an article in the Hillsboro (Ohio) Press Gazette, is an account of the 50th Class Reunion of the Clinton-Highland County Normal Class of 1923. Found on page 5 in the Social Events section, the original can be found here. Transcription follows with my notes [in italicized brackets].
