[1][2][3][4] Pallache worked with his father in trading activities and as an agent of Moroccan state at the time.
[4] When his father traveled and stayed in Morocco, David served as his deputy in the Netherlands.
[4] The scholarly biography A Man of Three Worlds: Samuel Pallache, a Moroccan Jew in Catholic and Protestant Europe did not find intermarriage between the Pallache brothers or sons and members of the Portuguese Sephardic community in the Netherlands.
"It seems significant that no male member of the Pallache family ever married a woman from the Portuguese community... it is surely significant that neither Samuel nor any of his heirs were ever to marry into the great trading families of 'the Portuguese nation'.
[9] Further, three years later, in 1646, Samuel Pallache, nephew of David, married Abigail (born 1622), sister of Judith Lindo.
