Queensberry questions

There a DUKE of Queensberry (Buccleuch and Queensberry) and there is a
MARQUESS of Queensberry but they are two separate people from what
seems like two separate families.

Questions:

1) Which one was created first?

Mario Glibic...

Both titles were created for William Douglas, 3rd Earl of Queensberry,
Marquessate in 1682, Dukedom in 1684. However, the titles had different
remainders, Marquessate to heirs male whatsoever, and Dukedom to heirs male of
his body (which was later changed to heirs male or female descended from the
1st Earl of Queensberry).

When the 4th Duke died, the male line descended from the 1st Duke and Marquess
was extinct; Marquessate then passed to a male line descendant of the 1st Earl
of Queensberry, while Dukedom went to the 3rd Duke of Buccleuch, descended
from the 2nd Duke of Queensberry through female line.

2) Any reason for the use of the same place in the title?

Mario Glibic...

It's not rare that a peer was given higher rank in peerage, with the the title
he already had. The Duke of Wellington is also Marquess of Wellington, Earl of
Wellington, and Viscount Wellington.

There is another similar case, there are two Dukedoms of Argyll one of
Scotland 1701 and one UK 1892.

There are also two earldoms of Mar, held by two different people.

Presently these are held by the same person, but it would be possible
for them to be held by two different persons .

3) Are there other examples of the same thing? (Only one I can think
of off hand is
Windsor (Duke of Windsor and Viscount Windsor)

Hovite...

There are two Earldoms of Mar.

Also the Dukedom and Earldom of Sutherland, once held simultaneously,
are now separated- the former was limited to the male line, the latter
can go through the female line.
