This collection consists of a diary, letters, and manuscripts, including two biographical sketches of John Joachim Zubly. The only original manuscript in the collection is the diary; the letters are copies made by I.K. Tefft and Archibald Smith from their respective personal collections. The diary, 1770-1781, is too fragile for use; a photocopy of the typescript is available for use. It covers Zubly's last years, with most of the entries devoted to his ministry. The correspondence includes a letter from Zubly to Noble Wimberly Jones his preparations of an address to the inhabitants on the 'alarming state of things;' a letter to John Houstoun and Archibald Bulloch; a letter to Governor Sir James Wright requesting repairs of the church and his home; a letter recounting what happened to Zubly during the Revolutionary War, lamenting the loss of his books, and stating that a nephew of the Bishop of St. David's is a wounded prisoner in his house; a letter to Captain Moon declaring that if Zubly is not indemnified for his losses, he will go to the law for redress; a letter from I.K. Tefft to William R. Sprague, in which Tefft writes he has not been able to write a sketch of Zubly for Sprague's Annals of the American Pulpit, but is sending papers that may help; Archibald Smith to I.K. Tefft telling what happened to most of Zubly's papers, and stating that he is sending copies of the few he has, as well as commenting on Zubly's diary. Also included are abstracts from letters to various recipients. A biographical sketch of Zubly by Edward J. Harden and 'Extract from the Biography of Button Gwinnett by Maj. Hugh McCall. Published in Sanderson's lives of the Signers, vol. iii p. 124-125-126,' with information on Zubly, are also included in this collection.
