This series contains correspondence between members of the Hall family and their extended family members from approximately 1742 to 1899. Letters were written predominately from New England (especially Philadelphia and Andover), Quebec City, and Montreal. The contents of the letters chiefly concern family news (including deaths and births), with some letters related to business, political and military events, and genealogy.

The correspondence in the series is grouped into a file for each family member represented - usually the creation of the letters, though some files also contain letters they received. There is also a file of correspondence related to family legacies and genealogy, as well as a file of miscellaneous letters, created by senders who were unidentified or who only appeared once in this series. The files in this series are arranged in approximate chronological order.
