All of those that I named have been through ownership changes too, so it seemed strange that you chose those as examples. Williams and Haas would have been better.
My point is that owners can call their company whatever they like. They can choose to retain a brand that reflects a previous owner or they can choose a new brand.
I can only say same to you as I said to Clatter... You do not understand the question, I can not figure out a way to ask it differently.
