Series II is an assemblage of Correspondence contained within the collection, received or exchanged by John Patch. A significant portion of the series is made up of letters exchanged by John Patch and Margaret Ann Gurley Poor, whom Patch would eventually marry; it appears that Patch frequently created facsimiles of his outgoing letters for his personal cache. Series II also contains two letter books—bound hardcover books containing transcriptions of letters from various individuals. It is unclear to whom many of these letters were addressed, as they are dated prior to John Patch's birth, but nonetheless the entries' handwriting appears to match his other compositions. Also of note are a series of catalog-type numbers assigned to each transcribed letter; it appears that each sequence begins with the senders' initials and ends with a series of numbers (i.e., "DK2986177").
