Marshall Danders

Marshall is deceased long before the start of The Sims 2, and the only indication of his existence is provided by the Pleasant family tree.

Marshall is the husband of Melinda Danders, with whom he had a daughter Diane Pleasant. Diane went on to become the mother of Daniel Pleasant, who is infamous for cheating on his wife, Mary-Sue Pleasant by conducting an affair with his housemaid, Kaylynn Langerak.

In MySims for Wii, a sim named Clayton Dander appeared, so it is possible, that he is a relative of the Danders family, but it is not proven yet.
