Richard Lloyd Tilghman to Agnes R.O. Tilghman from the Garrison of Mazatlan, 1848

This collection spans five generations of the Richard Tilghman family of the Gross' Coate estate in Talbot County, Maryland. It is divided into subgroups of land papers, papers of the four principal family members, and miscellaneous papers of the family. Although mostly correspondence, the collection contains land documents, wills, a ledger from Gross' Coate, genealogical material, and a draft of "Maryland: A Guide to the Old Line State."

The correspondence includes a variety of subjects such as life in 19th century Baltimore and the Eastern Shore; the Gross' Coate estate; the Navy; the Mexican War; death; family; farming; London and English society; travels across Europe; the Franco-Prussian War; sentiments after the Civil War; and World War I and its training camps.
