Including historiography in an essay, can be a challenge especially as most people haven't done it before. However, with a little bit of practice it will become second nature.
It is important to note that if you do include historiography in an essay it needs to be relevent to the question and add something to your essay - otherwise there is no point. Furthermore, there is no point saying 'historian x said this' and then not analysing it, as it won't get you any marks.
The whole point of historiography is to show the debate amongst historians on a particular subject.
For example when answering a question on how well successful was Elizabeth I in implenting her religious settlement you could use historiography like this:
Neale suggests that Elizabeth did not get the settlement she wanted as she was pressured by the Puritan Choir into a more Protestant settlement. However, revisionist historians largely reject this idea as they do not believe that a 'Puritan Choir' existed, and that Neale only used this idea as he wanted to further his concept that the House of Commons since this time grew in power.'
As you can see here I have managed to use a historian's view but then have analysed it and rejected it. This shows the examiner that you have a good grasp of the subject. Moreover, you can use this formula for any question regarding the religious settlement, or the political system.
Therefore, historiography should not be considered complicated as if you learn a couple of historians views, you can modify and manipualte them to fit most questions.
In addition sometimes historiography is not needed, for example if there is very little debate on what/why it happened.
Finally, historiography should not take up big bulks of your essay, as the examiner is more interested in what your judgement and evaluation of the events are, it is merely to support or further an argument.
