Are you asking about the Jane A. Hammond, born Aug 1842, Herkimer County, New York, who married Zela L. Soper, born Jun 1840, New York state (who served as a Sergeant in Company K, Wisconsin 19th Infantry Regiment during the War Between the States), and whose daughter named Harriet (maybe spelled Harriette nickname: Hattie) B. Soper, married Hiram Belden Simcock/Simcox? Note: The surname Simcock for Hiram's family changed spelling to Simcox around the 1890s.
I am descended from the Reverend Samuel Simcock and his wife Jane Ball Simcock, who emigrated from Staffordshire (Stoke-on-Trent area), England, eventually settling on a farm at Crystal Lake, Waupaca County, Wisconsin. Their son Isaac Simcock/Simcox was the father of Hiram Belden Simcock/Simcox.
By "Jane Simcox Boyle," do you mean Helen Jane Simcox, a daughter of Harriet/Harriet (Hattie) B. Soper and Hiram Belden Simcox? Helen Jane Simcox married a James W. Boyle and they resided in Chicago, Cook County, Illinois.
