The correspondence is arranged alphabetically by correspondent's last name. This series gives a broader understanding of von Briesen and his family, providing information as to particular members' location and activities.

Von Briesen's correspondence with his cousin Ernst Schenk (Schenk was the last name of many of von Briesen's family in Germany) particularly illuminates this point. Much of the correspondence is fact-filled in nature, caused in no small part by the English censors who made for irregular correspondence between the United States and Germany. Ernst's handwriting is difficult to understand, but its pattern, consistency, and near modern fraktur allow for relatively easy deciphering. The letters also reveal von Briesen's reverence and love for his family and mother-country. The letters on the whole tell about the war from both sides as Schenk's letters provide first-hand accounts of post-war Germany's disarray and severe food shortages (which von Briesen alleviated with food shipments) while von Briesen details the English censor and the stature of German-American citizens as "enemies" (or, at best "second-class-citizens").

In an unrelated but humorous matter, in a letter to Stanwood Menken concerning the choice of college for the grandson, von Briesen vehemently chooses Harvard over Princeton. In a letter dated April 10, 1920, there are three pages about why one should NOT go to Princeton.
