It was the Globe that exposed his Irish heritage hoax. - Tom
The Globe pieced together Kerry's genealogy through Ellis Island immigration records, other documents in Chicago and records from the former Austrian Empire. The paper hired Felix Gundacker, director of the Institute for Historical Family Research in Vienna, to examine and translate the German-language records.
Kerry's grandfather, who emigrated to the United States in 1905, was born in an Austrian town once known as Bennisch, which today is called Horni Benesov in the Czech Republic. Gundacker found birth records noting the 1873 birth of a Fritz Kohn and another record noting Kohn changed his name to Frederick Kerry on March 17, 1902. The Globe quoted Gundacker as "1,000 percent certain" that Kerry/Kohn was born to a Jewish family because the church records were on a page listing Jewish families.
