Thanes are noblemen in Scotland, not unlike Dukes and Earls in England. They, like knights of the old medieval times, pledged their loyalty to their Kings (called "ring-givers" in Anglo Saxon times), and in return the Kings took care of them and their families.
MacDuff is a thane, but he goes against his King, Macbeth, since he sees the destruction and chaos Macbeth is causing in the country MacDuff loves so much. He, therefore, travels to England to appeal to Malcolm, Duncan's next in line, and pledge his loyalty to him.
Google "thane" and you should come up with lots of sites. Try these as well: http://www.merriam-webster.com/dictionary/thane
I'll need a little bit more information in order to really help you out. In the play "Macbeth," a thane is an important landowner who has a lot of "pull" in the country and is in fairly close connection with the king. There are many thanes in the play: the Thane of Fife (Macduff), the thanes Ross, Lennox, Angus. . . . Macbeth himself is both the Thane of Glamis and the Thane of Cawdor (although there is a former Thane of Cawdor who was a traitor to Scotland and is executed, leaving the title to be given to Macbeth). So, first you need to be clear on what thane you are supposed to be writing about. Then, you can feel free to submit a specific call for help regarding the analysis of that particular character. Good luck!
'Thane' is a very very old word. I think your problem maybe that it can be spelt 'Thegn' aswell. The wiki link below has lots of stuff that you could use in your presentation. Just remember that you're talking and Medieval Tribalism and Feudalism. Loyalty to your King was the most important thing.
Just like we are told to be loyal to the American Flag and the things that it stands for, thanes were supposed to be loyal to their King, no matter what.
