The papers of New York City banker and businessman Samuel Flewwelling (1774 or 5-1849) primarily relating to property held by his wife, Julia Elvira Canfield Flewwelling (1791-1868), and him in the Western Reserve, later Ohio. Following Samuel's death, the properties were managed by William Mackay (1795-1873), a New York City businessman and the husband of Caroline Emma Canfield Mackay. The collections includes indentures, agreements, leases, deeds, statements and accounts, and correspondence. The papers are arranged chronologically in one series and consist mostly of documents concerning the conveyance land in the Western Reserve. The earliest document outlines the partitioning of land Judson Canfield and others purchased from the Connecticut Land Co. in 1799. Flewwelling acquired land from Canfield as early as 1815. Some of the later sales were among members of Flewwelling's family, including his father-in-law Judson Canfield, his brother-in-law Henry J. Canfield, and his brother- and sister-in-law Frederick Augustus Tallmadge and Elizabeth Canfield Tallmadge. Flewwelling provided mortgages to some of the purchasers of land, and the agreements contained in the papers spell out the payment terms. For many years, Royal Millard served as Flewwelling's agent in Ohio, and the collection includes many of his letters reporting on the buying and selling of properties and the collection of funds. After Millard died in 1854, Henry Canfield and William H. Canfield, a nephew of Judson Canfield, served as agents in Ohio, and their letters are also represented in the collection. Following Flewwelling's death in 1849, his brother-in-law William Mackay, a New York City businessman whose father William and brother Robert Mackay were wealthy Boston merchants, managed the Ohio lands for Julia Canfield Flewwelling. It appears that by the time of Mrs. Flewwelling's death in 1868 all of her and her late husband's Ohio land holdings may have been sold. Of particular interest in the papers are several documents that summarize Flewwelling's property holdings and detail the contracts and deeds he held.
