Hello Sharon (Rollinlibrarian), As a native of Harrellsville, my mother lives two doors down from where "Mrs. Wilder" lived on S. Quebec Street. She is deceased now (for about 15 years) but I bet she was the daughter of William J. Wilder and Martha Pierce Wilder. Her daughter is still living in Harrellsville on Taylor Street. Her name is Marion Wilder Johnson. If you called her I am sure she could help you with information on William Wilder. Thanks and Good Luck, Mike Vann Perry
