Mary liebte ihren Gatten über alles. In einem ihrer Briefe vom 9. August 1690 lesen wir: "They promise me all shall be ready by Tuesday next, that is the night of Mr. Butler’s reckoning, that with a fair wind you [Wilhelm III., der sich in Irland auf einem Feldzug gegen ihren Vater Jakob II. (VII.) Stuart befindet] may be here; though I think by your dear letter it is possible you may come a day sooner. … This letter, I hope will meet you at Chester, and I have one thing to beg, which is that, if it is possible, I may come and meet you on the road, for I do so long to see you, that I am sure had you as much mind to see your poor wife again, you would propose it; but do as you please, I will say no more, but that I love you so much, it cannot increase, else I am sure it would." (in: Francis Lancelott: The Queens of England and their Times, Volume II, id., p. 828).
In einem weiteren ihrer Briefe, geschrieben am 26. August 1690, lesen wir: "… I think in what perpetual danger you are. I am in great fear, count the hours and the moments, and have only reason enough to think, so long as I have no letter, all is well. … I must play twice a-week, nay, must laugh and talk, though never so much against my will. I believe I dissemble very ill to those who know me, at least it is a great constraint to myself, yet I must endure it. All my motions are so watched, and all I do is so observed, that if I eat less, or speak less, or look more grave, all is lost in the opinion of the world. So that I have this misery added to that of your absence, and my fears for your dear person, that I must grin when my heart is ready to break, and talk when it is so oppressed I can scarce breathe. … if you love me as you make me believe, and as I endeavour to deserve a little by that sincere and lasting kindness I have for you. … beseeching God to bless you, and keep you from all dangers whatsoever; and send us a happy meeting again here upon earth, and at last a joyful and blessed one in heaven, in his good time. Farewell, do but continue to love me, and forgive this taking up so much of your time by your poor wife, who deserves more pity than ever any creature did, and who loves you a great deal too much for her own ease, though it can’t be more than you deserve." (in: Francis Lancelott: The Queens of England and their Times, Volume II, id., pp. 832-834).
"On the fifth of September, 1690, William embarked at Duncannon fort … the next day he arrived in King’s Road, near Bristol. Two days afterwards, the Queen received intelligence of his landing … [in ihrem Brief vom 8. September 1690 lesen wir:] '… Nothing can express the impatience I have to see you, nor my joy to think it is so near. I have not slept all this night for it, though I had but five hours’ sleep the night before, for a reason I shall tell you.' ... On the ninth of September, Mary with infinite joy, met her husband at Windsor…" (in: Francis Lancelott: The Queens of England and their Times, Volume II, id., p. 834).
