All of my notebooks are packed at the moment, we will be moving in a month or so and I packed them first, so that I would not work on genealogy, instead of packing. You can see how well that worked. My husband descends from Charles Miller. Not much is known about Charles, but the Thomas family are well covered in a couple of publications. The Thomas Family, Hilltown, Bucks County, Pennsylvania by Edward Matthews, Published by Arthur K. Thomas, Lansdale, Pennsylvania, 1884. I think I found this book at the Family History Library in Salt Lake City. Maybe they have it on-line by now. Another book was done by Doris Osterheld, but I don't think it circulated beyond immediate family. How are you related, perhaps it would be of interest. Doris' book is about a younger Charles Miller and Catherine Jane Butts, his wife.
