Anne was born on 30 April 1383 and was baptised at Pleshey, Essex, sometime before 6 May. Her uncle, John of Gaunt (third son of King Edward III), ordered several payments to be made in regards to the event.[2]
At the death of her brother Humphrey, 2nd Earl of Buckingham, in 1399, Anne was the co-heiress together with her two sisters Joan and Isabel, to his estates and titles.[3][4] Anne became the sole heiress of the family's estate and titles in 1400, as one of her sisters, Joan, having died on 16 August 1400, and the other, Isabel, having become a nun.[5]
She was subsequently recognized (and thereafter succeeded) as suo jure Countess of Buckingham, Hereford and Northampton as well as succeeding to the titles of Lady of Brecknock and Holderness.[6][7]
Anne did, however, not use these titles, and instead styled herself as Countess of Stafford.[8]
Anne married three times. Her first marriage was to Thomas Stafford, 3rd Earl of Stafford (1368 – 4 July 1392), and took place around 1390. The couple had no children. After her husband's death, Anne married his younger brother Edmund.
