Don’t be intimidated by the facts, or the personalities that you discover. The facts are a starting point, not a straitjacket. Remember that even biography is an inexact science.
Once you have done enough research to get a strong sense of the time and place you are writing about, and the people who lived there, you need to free yourself from the idea that you need to be 'faithful to the facts'. You must get the facts right, yes, but you actually need to be unfaithful to them. Being historically accurate means that you don't change the dates of battles, the deaths of known historical figures, or make other blunders which are anachronistic and undermine your credibility as a historical fiction writer. (This does not apply if you are writing altered history, of which more in a later post. But altered history has as much in common with fantasy as it does with this genre.)
However it is possible to decide that - for example - Thomas Cromwell was beaten and despised by his father, and this was a formative element of his psychology, as Hilary Mantel does in Wolf Hall, or that Charles II rewarded an obscure physician for saving his favourite dog, as Rose Tremain does in Restoration. If you don't make such leaps of imagination, then you might as well write a text book, which is fine, but it's not fiction.
Biographers create a story: the story of the life of their subject. They research that person's life and perspective, using letters, their own work, their own diaries, the diaries of others, and perhaps interviews if their subject is still alive or died recently. Once this work is done, the biographer uses supposition to try to enter the consciousness of this person. They may dramatize or even invent certain scenes to bring the 'story' alive. Some are more audacious than others - Peter Ackroyd is well-known for using the devices of a novelist to explore the lives of writers like Charles Dickens.
Fiction writers go beyond supposition - they invent. You have just as much right to do this if your book is set in 1614 as you do if it is set in 2014. And this still applies if you are basing your story on the lives of real people.

You can't write historical fiction politely. You have to force your way into the past, and claim it as your own, no matter how crazy or impossible this may seem. This is what Fay Weldon said to me when I was working on an early draft of my novel Dark Aemilia 'If you are going to put William Shakespeare in your book, he has to be your William Shakespeare, and no one else's.'
