I thought I would pass on this piece of trivia about David de Aguilar, brother of H.H. Moshe Raph. de Aguilar. An important event in the history of the Portuguese Jewish Community of Amsterdam was the so-called “Del Sotto Affair” in the 1670’s, that grew out of the death of the wealthy Jacob Del Sotto, alias Del Monte. The facts of the affair were complex, and included a lost Will, the refusal of Jacob’s young widow to enter into a levirate marriage due to romantic love, a split in the community, etc. A key witness to the events was Jacob’s bookkeeper of 30 years, a David de Aguilar. Thanks to Ton Tielen posting David’s entry into the Dotar membership (attached below) and Lydia Hagoort’s accurate citations in her Studia Rosenthaliana article “The Del Sottos, A Portuguese Jewish Family in Amsterdam in the Seventeenth Century,” it looks like David de Aguilar, the Dotar member, and Jacob Del Sotto’s bookkeeper are one in the same. This is the link to the relevant page in the collection of Notary J.
