Jane Grey Books

“Though wildly different in both character and tastes, Jane and Mary shared a common bond aside from the royal blood which flowed in their veins: their religious devotion was unswerving, and the dominant factor in both of their lives. For Mary, the situation was heartbreaking. Jane's mother, Frances, had been a close childhood companion. Frances, like her husband and her daughter, was a Protestant, though perhaps not as fervent in her faith as her husband and eldest daughter. Despite the fact that she and Mary were on opposing sides of the religious fence, to all appearances their differing beliefs had never driven a wedge between the cousins. Frances was a seasoned courtier, and as such she was well skilled in the art of diplomacy. It seems likely, therefore, that when she was in the company of her childhood friend, the two women tactfully avoided conversing on the subject of religion. After all, there were many at court who managed to maintain friendships with people who held differing religious beliefs, and Mary had also been friendly with Jane's step-grandmother, Katherine Willoughby. But it was quite different with jane, for though Mary had tried her best with the teenager, and had done her utmost to be affectionate, the relationship was not a harmonious one. The age gap between them meant that to Jane, Mary was probably more like an aunt than a cousin. Mary may have been twenty years Jane's senior, but it was not age that lay at the heart of the matter; the reason for the distance between the two cousins was perfectly simple: religion.”
