Swarm question

[Faith Farm]

One of my hives swarmed today and my wife and I were able to capture it. When we put it in a hive we saw the queen on the top bars. I put a queen in this hive last summer when they failed to re-queen after a swarm. (So far I am doing great at producing swarms!) She was marked but the queen I saw today was not and I am sure their have not been any swarms since the requeening, other than today. What is going on? Also when I removed the swarm from the tree there was a very large cluster of bees and a smaller separate cluster. I put both in the hive. Could both have contained queens?

First, many introduced queens are superceded "replaced" shortly after introduction. The marked one probably was.

Secondly, yes, there may be as high as 5 or 6 queens in a swarm. The bees will choose which one they want to keep.
