Sonja Borus was born on February 23, 1927, in a Berlin that still felt like a world of possibility. Her parents, Abraham and Beila Borus, had immigrated to Germany from Galicia after World War I, seeking a new beginning.

In this move, Abraham followed his family who had already settled there: his father Yosef Borus, his wife Chayele Birken, and Abraham’s siblings—Lippa, Dora, Frieda, Markus, and Paula. This large, established presence of aunts and uncles formed the bustling, loving backdrop of Sonja’s early years.
