Who is not a member of the family for the purpose of the Madhya Pradesh Accommodation Control Act, 1961?

Section 2(e) of the M.P. Accommodation Control Act, 1961 names the unmarried daughter, the unmarried sister and the grandfather as members of the family. A grandson is not named, so a "Grandson living separately" is not a member of the family unless he is shown to be a relation dependent on the landlord.
