Where are you living? I have an extensive database with information on plenty of families from the notary archives. Also, many families in Aruba and Curaçao are now into genealogy and a lot has been looked up already. If you do not mention what you need specifically, it is difficult to send you in the right direction. Originals of the civil registrar should be in Aruba and Curaçao, as I said earlier. Other original material might be in Aruba, Curaçao or the Netherlands. Depends what you are looking for. Land purchases are either in Aruba (kadaster) or Curaçao. Older ones, usually before 1848, are in the Netherlands.
