Update 7/21/15 Because Wertheimer is connected to Oppenheim/Oppenheimer, I'll add a little about that surname because it connects strongly to Wertheimer from this same book.
 
Oppenheim/Oppenheimer is an Ashkenazic surname taken from the German town of Oppenheim on the Rhein-Hessen.  Jews first settled there in the 13th Century.  JE and UJ have many biographies from Germany, Austria and England, beginning in the 17th century.   That could explain why not all Oppenheimers are related by DNA.  LBI has Oppenheim family trees beginning in 1556, 1633, 1676 and 1825.
