Just thought I'd give you a heads-up on one of the Huff's. My ggreat grandmother's sister, Leah Ranck was married to a Joseph Huff, who died in about 1922 in Allenwood, Union County, PA. They're all buried together in a family plot in Allenwood Cemetery and I have their pictures (their plots) if you later find a need for them. My ggrandmother's husband, Joseph W. Smith, still illudes me and I don't know why she's buried witht the Huff's instead of her own husband - at least not yet. I think Joseph Huff's father was a William but I'm not sure about that one - he may even be the same individual as you write about. My cousin know's of a related family member up there that know's a little more about that part of the family.
Hope this helps you even a little bit.
