Letter from the young Mary, Queen of Scots,
to her mother, Mary of Guise, c.1550 
(NRS reference: SP13/71)

Summary translation:

Madame, 

the King sends to you Monsieur de Breize, who has, as you know, heartily done me very humble service, and from day to day exerts himself in doing whatever business may be agreeable to me, which makes me heartily pray you to give him a good reception, and to let him know that I have desired you to do this. He has instructions from the King to relate to you fully all the news, which prevents me from writing you a longer letter, except to beseech you very humbly to keep me always in your good grace, as

Your very humble and very obedient daughter

Marie
