Abstract: We discuss family unification in grand unified theory (GUT) based on an GUT gauge group broken to its subgroups, including a special subgroup. In the GUT on the six-dimensional (6D) orbifold space , three generations of the 4D Standard Model Weyl fermions can be embedded into 6D bulk Weyl fermions in an second-rank anti-symmetric tensor representation. 6D and 4D gauge anomalies can be canceled out by considering proper matter content without 4D exotic chiral fermions at low energies.
