Ancestry of Elizabeth Du Pont Bayard (Mrs. Thomas Francis Bayard) for Her Children

Compiled by George Valentine Massey II and published in the mid-20th century, this genealogical record was created to document the complex ancestral lineage of Elizabeth du Pont Bayard for the benefit of her descendants. It serves as a meticulous tracing of the du Pont family's roots, a lineage deeply intertwined with the industrial history of the United States, specifically through the E. I. du Pont de Nemours and Company. The work functions as both a private family archive and a secondary resource for historians interested in the genealogical ties of prominent American dynasties.

The volume reflects the mid-century trend of private press genealogical research, where family historians sought to preserve heritage through formal, printed documentation. Massey, known for his expertise in regional genealogy, approached the task with a focus on archival accuracy, aiming to solidify the narrative of the Bayard and du Pont connection. While it remained a niche publication intended for family members and specialized genealogical collections, it is noted for its precision and the significant social standing of the subjects involved.
