I come from William's brother Patrick Hanifin (I have different spellings for him) I have a copy of a picture that was given to my Great-great Grandmother Mary Jane Hanifin from her cousin "Kate". I always assume that was William's daughter now with what info you gave I believe it is. I don't know Patrick's or William's parents. But know for a time William lived with Patrick and his wife before getting married himself. I would love to discuss our family roots with you more.I can give you some more info on Patrick.
