I've been looking for some Willeys as well.
My gggrandmother was Harriet WILLEY (Streeter)
Her mother was Elizabeth (Crawford) Willey, daughter of Josiah and Elizabeth CRAWFORD.
(I think it might be relevent to the Crawford County, as Josiah Crawford seems to have been a land-holder)
I know that Harriet Willey b1867 d1937 was the daughter of Elizabeth Willey, but thats where I dead-end.
I hope that gives a clue to someone, if anyone can help me fill in the blanks, feel free to e-mail me.
