Dietz identifies this family as descended from David von Hildesheim, who married Sara Wohl in 1620 and adopted her family's surname. Being descended from a family called Hildesheim with origins in the Main region (Hanau), I compared my Y-DNA results with a couple of Wohls on ftdna.com and found striking similarities. (There are a number of differences in frequently mutating genes, but I reason this should be expected after about 16 generations.)
Dietz identifies David's father as Elias Salomon (Eliyahu Shlomo ben Yaakov, d. 1620), whose gravestone is embedded in the wall of the Teichstrasse cemetery in the town of Hildesheim. This name corresponds to "Salomon jude von Berg" (Moritzberg) who was one of the thirteen Jews who, with the court Jew Nathan Schay, are recorded to have been afforded residency rights in Hildesheim by the imperial court in 1601 after an exclusion that lasted with varying enforcement almost 60 years.
The possibility of this connection has been confirmed by the historians at http://www.steinheim-institut.de/cgi-bin/epidat?id=hld-7&lang=en.
While it is impossible to conclusively prove that branches of the Wohl and Hildesheim families are descended from Salomon, I think the likelihood is high based on the Main locale, the small number of Jews residing in Hildesheim in the early 17th century, the history recorded by Dietz, and the DNA evidence.
I wouldn't know how to integrate this speculation into a family tree, but it should be of interest to anyone researching the Hildesheim and Wohl families. However, note that there are families that share the Hildesheim or Wohl surnames but are unrelated.
