William & Phoebe (Smith) Pitcher - NY, WI, IA

I am looking for anyone who would happen to have any information on William and Phoebe.I read that they were married Feb 1 1855 in Chautauqua Co. NY.They then moved to WI - near Madison - and finally settled in Butler Co. IA.A Minerva Pitcher is buried in the Myrtle Cemetery near Poland, Chautauqua Co. in the same burial plot as Faba Smith.Minerva died young, 25, and was married to a William Pitcher.I am wondering if a widowed William married Faba's sister, Phoebe, daughter of Hiram and Lydia (McGowan) Smith.
