These persons (Sara van Geldere-Frijda and Benjamin Frijda) are listed as residing at the same address. The source does not provide information about how they were related to one another.
However:
Levie Frijda, grandfather of Sara van Geldere-Frijda and of Benjamin Frijda, was married twice. Sara’s father Hertog Levie Frijda was born in the 1st wedlock and Benjamin’s fater, Izaak Levie Frija was born in the 2nd wedlock. Both fathers were actually half-brothers. So Benjamin was a “half-cousin” of Sara van Geldere-Frijda.
