Edward Stafford

Mary's marriage to William Stafford (d. 5 May 1556) may have resulted in the birth of two further children:[17]

• Edward Stafford (1535–1545).
• Anne Stafford (b. 1536?–?), probably named in honour of Mary's sister, Queen Anne Boleyn.

however if there were children of the marriage, nothing further is known of them.[9][10]
