You are correct about Lucy being daughter of William and NANCY. That's what I meant to type in my earlier email.
I've been to Coryville to photograph Champlin gravestones in several area cemeteries. Coryville is halfway between Eldred and Smethport, Penn on Route 446. The 446 starts at Route 417 just east of Portville and heads due south.
Can you give me info on Lucy's children?
I am preparing and will email you directly, bios on Lucy and ancestors.
