the assistance of the affidavit books, other sources must be consulted. In a document undoubtedly used to write his 1887 Historical Record article on plural marriage, independent historian Andrew Jenson referred to Sylvia as a “formerly the wife of Windsor Lyons.”15
He also penned: “Sessions, Sylvia Porter, wife of Winsor [sic] Palmer Lyon, was born July 31, 1818. . . . [She] Became a convert to ‘Mormonism’ and was married to Mr. Lyons – When he left the Church she was sealed to the Prophet Joseph Smith.”16
A second corroboration is found in the 1915 statement from Josephine. She remembered her mother also “told me that I was the daughter of the Prophet Joseph Smith, she having been sealed to the Prophet at the time that her husband Mr. Lyon was out of fellowship with the Church.”
Accordingly, these documents place the sealing after Windsor’s excommunication. Windsor had a falling out with Stake President William Marks over a financial negotiation in the fall of 1842. In the end, Windsor sued Marks in the civil courts—a violation of Church standards since such matters were to be resolved between members within the Church. In response, Marks brought Windsor up for a Church court. On 19 November 1842, Windsor was excommunicated and left Nauvoo for a few weeks.18
Currently, no documentation of a legal divorce between Windsor and Sylvia after his excommunication has been found.
