From Nov 1 1858 (when the East
India Company sold its Indian possessions to the monarch) till the end of 1876 (after which she styled herself the Empress of
India),
Queen Victoria was the monarch of
India and ruled through her viceroys. In this period, she made the then Calcutta the
Royal capital (of course, it became the Imperial Capital later). So, I guess, in that period, she was the
Queen of
India (in addition to her other territorries).
I am not clear what the original poster was asking, though.
On the second point, I think what is called the middle name is culture dependent: I know of lots of examples of multiword first names and multiword last names where the middle ones are not considered middle names. Thus, I knew a Arifa
Ali Khan with
Ali not being the middle name, but just the first word of the last name.
