I desended from Wilby's of Onondago Co. NY in my grandmothers notes I found a reference to a grandfather Tierney. My grandmother's name was Pearl Alice Wilby and my Aunt's name is Alice Frances... Please keep me in mind if you come across any Wilby. I'd be interested to know more about your Tierney's. I don't have any other info other then the reference "grandfather Tierney".
