I would like to find out any information of my family name 'dos santos'. The information I have is that my grandmother was called Maria Nunes of the Jarimba family and she married my grandfather Manuel Rodrigues dos Santos, who together with 12 other crew members disappeared whilst fishing I think in the year 1949 or 1950 not sure. They were from the island of Madeira, of the village Machico. I would like to trace my families history to as far back as it can go. My father was their son Joao Rodrigues dos Santos. They were four children. Any information from the archives in Portugal or Madeira would be greatly appreciated.
