Her parents having fled Nazi Germany, she'd been brought up in the mistaken belief that "all the Jewish records were destroyed". In fact, she has been able to trace both sides of her family back to late-18th century Galicia, and is continually discovering modern-day family as well, in great part thanks to the wealth of 21st century resources.
