We have  family charts or “Y Trees” for Frankfurt Jewish families, including families that moved elsewhere (Prague, Vienna, etc.)   These surnames are represented on the charts. The code in parentheses after a name indicates the Y-DNA haplogroup.  If a chart is too small to read, just click once or twice and it will be legible.    Please keep in mind that our “Y Trees” differ from a traditional family tree, just as  traditional genealogy differs from genetic genealogy.  (See the explanation of the charts here).
