We spell our name with two "f"s. However there was a Sabilla Wolf who married into the family many years ago. In my research I also have a few Wolfs who married into the Kaltz family. My mother was a Kaltz but I am having a difficult time relating her to any of the other Kaltz families in the area. It seems to be an unusual name so I would have thought I would have had an easier time of it.
My grandfather George Kaltz came from Bueren, Prussia as a small child.
