Short answers, pulled from the story.
Mary Boleyn likely entered the world between early 1499 and late 1500 at Blickling Hall. Her family home was Hever Castle in Kent, where she spent her formative years alongside brother George and sister Anne.
Thomas Boleyn served as a wealthy diplomat while his wife Elizabeth Howard came from the powerful Howard lineage. Mary received a standard education for noblewomen of her rank during these childhood years including arithmetic grammar history reading spelling writing dancing embroidery etiquette household management music needlework singing and games like cards archery falconry riding and hunting.
Rumors circulated that the King fathered one or both of Mary's children during their affair though Henry never acknowledged either child despite acknowledging Henry FitzRoy from another mistress Elizabeth Blount. The relationship began sometime after her marriage but ended before she became pregnant again without records specifying how long this liaison lasted between 1520 and 1534.
Mary secretly married William Stafford in 1534 despite his status as an Essex landowner's younger son with minimal prospects. Their union appeared driven by love rather than social advancement when Mary became pregnant which led to family disownment and court banishment after Queen Anne reacted furiously upon discovering the marriage.
Mary herself died between the 19th of July and the 30th of July 1543 most likely at Rochford Hall in Essex. Her death came seven years after exile without any known cause recorded in surviving documents.
