Hello! I don't think there's a connection here, but thought I would try anyway. My great grandmother's mother's maiden name is listed as 'dos Santos'. My great grandmother was supposedly born on Cape Verde in 1892 or 1893. Her fathers name was Jose Luiz Moraes (or Morais). She had a sister named Margarita, and possibly a sibling named Paulina or Paulino. My great grandmother married my great grandfather, Luiz Daniel Pereira. They then had 3 children (Matthias, Solteiro and Maria da Luz) before moving to Massachusetts and having many more children. If there is any connection, please let me know! Thank you for your time!
