Brother of Zadok

David Werkendam (b1890) my grand uncle, was the brother of my great grandfather Zadok Werkendam (b1888). His other siblings were Engelina, Hartog, Johanna (Anne), Simon and Esther Werkendam. I would dearly love to see an image of him to add to our Werkendam family tree. Any photos of Isaac and Engelina would be very much appreciated also.
