Esther Ranzten launches Who Do You Think You Are show

Responding to a growing interest in family history research, the Jewish Genealogical Society will be exhibiting at the Who Do You Think You Are? show at London's Olympia this weekend.

JGS education officer Jeanette Rosenberg said "people are studying their genealogy to find out where their family have got to. They are keen to connect with living relatives all over the world, since frequently families were separated by the Holocaust."

This year, the show organisers have created a specific website area to help Jews trace their ancestors.

Celebrity guests include Esther Rantzen, whose family history includes fraud, bigamy and a connection to a diamond magnate. Her research ended in Poland, where she "discovered a string of tragedies" and traced her surname back to 1769.

Ms Rosenberg added that "the advent of online records has certainly made some aspects of genealogy research easier. However, only a proportion of records are online. Most genealogical research is undertaken in local archives, record offices and cemeteries."
