Nellie Martin, 30, was a "pupil nurse" at the St. Francis School of Nursing at the time of the 1910 Federal Census. She was born in Pennsylvania and her parents in Ireland.

"Eleanor B. Martin" is named in a 1922 history of the Pittsburgh Red Cross as a St. Francis graduate and a nurse at the University of Pittsburgh Base Hospital, No. 27. She served with the American Expeditionary Forces during World War I, and is named in this article: Nurses Given Great Ovation By Pittsburgh.

The WWI Veterans Service Compensation Card of Eleanor B. Martin indicates that she was born in Reynoldsburg, Pennsylvania on September 4, 1883. She was called into active service and served overseas from September 27, 1917 to March 12, 1919. Honorably discharged May 5, 1919. Subsequent service April 7, 1922 - April 9, 1922.

This is the longer application for her WWI Veterans Service Compension, filed in 1934, at which time she lived in Monmouth, New Jersey:

In the 1940 census of Allegheny County, Eleanor Martin, Nurse, 64, born in Pennsylvania, was living at the St. Francis Nurses' Home, and she was a Private Duty Hospital Nurse. The record indicates that in 1935, she had resided in Monmouth County, New Jersey.

The U. S. Veterans' Gravesites database states she was born on September 4, 1882, and served as a nurse in the US Army during World War I, starting August 20, 1917. She died January 17, 1968 and is buried at Dayton National Cemetery.

An online genealogy confirms that this woman, exact birthdate unknown, but possibly as early as 1876, is buried at Dayton National Cemetery. She was the daughter of Michael B. Martin (1835-1894) and Mary Mulvany Martin (1842-1900). As was the case with some of the other World War I nurses, she might have understated her age so she could enter the service. (The age limit for WWI is unknown, but at the beginning of WWII, it was 40, later raised to 45.) Siblings named in the genealogy are Bernard, James, Katie, Michael Joseph, Mary, Margaret, Delia Gertrude, Agnes E., and Frank D.
