Around 1326, Stafford married his first wife, Katherine de Hastang. Katherine was the daughter of Sir John de Hastang, Knight, of
Chebsey,
Staffordshire. Ralph and Katherine had two daughters: • Margaret Stafford, married Sir John de Stafford, Knight, of "Broomshull" (
Bramshall near
Uttoxeter, Staffordshire) and
Amblecote in the parish of
Old Swinford, Worcestershire, ancestor of several prominent Stafford lines, most notably Stafford of
Hooke in Dorset, Stafford of
Southwick in Wiltshire and Stafford of
Grafton in Worcestershire. • Joan Stafford, married Sir Nicholas de Beke, Knight. He later sensationally abducted
Margaret de Audley, 2nd Baroness Audley, daughter of
Hugh de Audley, 1st Earl of Gloucester and
Margaret de Clare, who was worth at least £2,314 a year, more than ten times his own estates. Her parents filed a complaint with King Edward III of England, but the King supported Stafford's actions. In compensation, the King appeased Hugh and Margaret by creating Hugh the 1st
Earl of Gloucester. Margaret de Audley and Stafford married before 6 July 1336 and they subsequently had two sons and four daughters: • Ralph de Stafford (d. 1347), married
Maud of Lancaster, daughter of
Henry of Grosmont, 1st Duke of Lancaster and
Isabel de Beaumont in 1344. •
Hugh de Stafford, 2nd Earl of Stafford, born circa 1336 in
Staffordshire, England, married
Philippa de Beauchamp; they were the ancestors of the
Dukes of Buckingham (1444 creation). • Beatrice de Stafford, born circa 1341 in Staffordshire, England, died 1415, married firstly, in 1350,
Maurice FitzGerald, 2nd Earl of Desmond (d. June 1358); married secondly,
Thomas de Ros, 4th Baron de Ros, of Helmsley; married thirdly Sir Richard Burley,
Knt. • Katherine de Stafford, born circa 1348 in Staffordshire, England and died in December 1361. On 25 December 1357, she married Sir
John Sutton III (1339 – c. 1370 or 1376), Knight, Master of
Dudley Castle, Staffordshire. Burke reports that she died without issue. However, Burke is often erroneous and incomplete, and later evidence supports that she is the mother of
John Sutton IV, 3rd Baron Sutton of Dudley, probably having died in childbirth. ==Death==
