Geoffrey Landgraab

Malcolm Landgraab II is a Maxis-created Sim who is shown on the Landgraab Family tree as the husband of Marion Landgraab and the father of their son Malcolm Landgraab III. According to the family album of Malcolm IV, it is Malcolm II that took care of him after his parents died. It is speculated that Malcolm could, perhaps, be the son of Malcolm Landgraab, who is featured as the villain in the console games of The Sims Bustin' Out, as well as the PC game SimCity 3000.

Malcolm's grandson, Malcolm Landgraab IV can be found in Bluewater Village (the default shopping district from The Sims 2: Open for Business). He lives in a large mansion and owns two successful businesses.
