In 1477 Margery wrote a letter to her John
pleading with him not to give her up, despite her parents' refusal to
increase her dowry.

Addressing her “ryght welebeloued Voluntyne” (right
well-beloved Valentine), she promised to be a good wife, adding: “Yf
that ye loffe me as Itryste verely that ye do ye will not leffe me” (If
you love me, I trust.. you will not leave me).

Her beloved might have had his mind on business, driving a
hard bargain for her hand in marriage, but Margery still had her sights
on romance, and so secured her place in English history.
