Small collection of letters relating to Julia B. Newberry and her relatives, 1832-1880 and also undated, plus letters of credit from Julia's bankers, 1872-1885. There is one letter from Julia's father, James Clapp, to Henry R. Mygatt in 1832, in which he discusses a conversation with President Jackson, the political climate in Washington, and his opinion on the threat of nullification in the south. A second letter from Clapp to Mygatt in 1852 contains Clapp's thoughts on the Wilmot Proviso and the future of the Union. The rest of the collection contains photocopies of a transcription of Mary Butler Devereux's diary of the mid-nineteenth century, a tiny scant diary kept by unknown persons (1876, 1903), a photocopy of genealogical research on the Butler, Devereux, Kernan families (1921), and a photocopy of Probate Court record in 1877 regarding Walter L. Newberry's estate.
