William Tayler's letters (1801-1807) were written to Relf; and at some undetermined time, Reif also acquired the letters which his father-in-law, William Poyntell, had written to his wife from abroad in 1802 and 1803. It is presumed that after Relf's death the letters passed to his daughter Ann (born December 16, 1803; died May 15, 1832 at Norwalk, Connecticut), who on October 9, 1821 had married Jackson Kemper (1789-1870), then a Protestant Episcopal priest in Philadelphia. Kemper later served as a pioneer Episcopal missionary in the Midwest, and as the first diocesan bishop of the Episcopal Church in Wisconsin. The originals of the Poyntell and Tayler letters in this microfilm remain in the possession of the descendants of Bishop Kemper and Ann Relf Kemper.
The handwritten biographical sketches were loaned to the Historical Society in September 1979 by Samuel Relf Durand along with photographic copies of portraits by Rembrandt Peale of Samuel Relf and William Poyntell. Durand also loaned for copying a letter written by William Tayler to Samuel Relf on September 5, 1805, with the request that these items be added to the Tayler and Poyntell letters previously loaned to the Society for microfilming by Mrs. Charles B. Jackson of Nashotah, Wisconsin, also a Poyntell-Relf-Kemper descendant.
