Over the decades of my genealogy research and DNA studies, a number of people have been supportive and provided data, guidance, or their expertise, which I would like to acknowledge. Most important, the participants in the Bacharach DNA study have shed light on the history and migrations of an illustrious family from the Middle Ages to now. The contributions of other genealogists and experts who helped interpret old German handwriting, identified new sources of records, translated Russian, and provided historical context cannot be overstated. Among them are: Janet Akaha, Ralph Bloch, Lars Menk, Karen Franklin, and Mikhail Bakhrakh.
