As will be noted in the advertising columns, married life with John C. Van Sise is a sorry failure. On Sept. 6 last, the Rev. Samuel H. Seem, of the Central Church, tied him and his bride in a good, hard knot, but thus soon the wife, who was Mrs. Elizabeth Smith, is sorry the hitch was made, and refuses to live with her spouse. Van Sise is a man of 50 and well to do, and it is claimed that the wife wants his to sign over his property to her before she returns.
