Yaakov Pearson is one of David Pearson's 6 children (yes, they are below).
David Pearson is one of Bernard Pearson's 5 children (Frank, David, Mimi, Ruth, Joel - all but Mimi have their own children too)
Bernard Pearson is the step-son of one of my grandmother's (Hede Ritzewoller Cohen) sisters (Tante Elsa, the other sister is Tante Llena)
That makes Bernard Pearson my father Dieter's 1st cousin. Bernard's blood father and his wife Elsa perished in the Holocaust. Bernard escaped on kindertransport and later lived with my father's family in Philadelphia. At Bernard's wedding in the mid-1950s, my grandparents, Bernard's aunt and uncle gave him away. My father and Bernard were almost like brothers and my sisters and I grew up celebrating holidays with the Pearsons in the Philadelphia area.
