Some journalists and newspapers have started to refer to fathers as Srs and sons as Jrs. In the West it is normal practice to give father’s name to eldest son and mother’s name to eldest daughter. Father is referred to as Sr and eldest son is referred to as Jr. If there are three generations of men with the same name, man of first generation is called I, man of second generation is II and man of third generation is III.
In India sons are not named after their fathers and hence it is incorrect to call father Sr and son Jr. Bal Thackeray is not Thackeray Sr and Uddhav Thackeray is not Thackeray Jr. Similarly Feroz Khan is not Khan Sr and Fardeen Khan is not Khan Jr.
