William Lyon

William Lyon (1753-1816) married Martha Foster in 1778.  They were both members at St. Andrew’s Street; their daughter, Martha, married William Foster, Flower’s friend at St. Neots.  Lyon took over the grocery business of Stephen Harrison (father-in-law of the celebrated Cambridge mayor, John Mortlock) in 1776 and remained in that capacity for most of his life. He also served as the Cambridge agent for the Phoenix Fire Assurance Company, which advertised frequently in the Cambridge Intelligencer.  See Church Book: St. Andrew’s Street Baptist Church, Cambridge 1720-1832 (London: Baptist Historical Society, 1991), 137, 153.
