Just before the last Jewish New Year, Simon Glassberg flew from Canada to Israel to meet his sister Hilda Shlick (nee Glassberg) whom he thought had died in the Holocaust. In 1999 another Canadian brother, Karol, entered Hilda’s details into the Yad Vashem database, to be discovered only in 2015 by Hilda’s Israeli grandson David Shlick.
