Information:  - Edgar I (943  8 July 975), known as Edgar the Peaceful or the Peaceable, was King of England from 959 to 975. He was the younger son of King Edmund I and his Queen, Ælfgifu of Shaftesbury.  - Ralph the Timid , also known as Ralf of Mantes ( died 1057 ) , was Earl of Hereford between 1051 and 1055 or 1057 . His mother was Godgifu , the daughter of King Æthelred the Unready and his second wife Emma . His father was Drogo of Mantes , Count of the Vexin , who died on pilgrimage to Jerusalem in 1035 . Ralph came to England with his uncle , the future King Edward the Confessor , in 1041 . He attested three charters as earl in 1050 , and his earldom was probably located in the east midlands , where the lands of his wife Gytha were located . He was a benefactor of Peterborough Abbey . When King Edward quarrelled with Earl Godwin in 1051 , Ralph raised the levies of his earldom to support the king . Godwin and his sons were forced into exile , but they returned the following year , and Ralph and Earl Odda commanded the fleet raised to resist them , but they were unable to prevent their return in triumph . Later in 1052 Godwin 's son Sweyn died on pilgrimage to Jerusalem , and it was probably at this stage that Ralph was given Sweyn 's earldom of Hereford , which included Oxfordshire . In 1055 Ælfgar , the earl of East Anglia , was exiled and allied himself with the ruler of Wales , Gruffydd ap Llywelyn . Ralph met them in battle on 24 October , but suffered a disastrous defeat , and the invaders sacked Hereford . It was later claimed that Ralph and his Frenchmen started the rout , resulting in his insulting nickname , ' The Timid ' . Godwin 's son , Harold , the future king , then chased the invaders back into Wales . Ralph died in his early thirties on 21 December 1057 , and was buried in Peterborough Abbey . Ann Williams suggested that Ralph probably lost his earldom to Harold after his defeat in 1055 , but in the view of Frank Barlow he held it until his death . Ralph 's son Harold was one of the royal children brought up by King Edward 's wife , Edith . Ralph was on good terms with the Godwins , and his son may have been named after the future king and been his godson .

He married Goda, daughter of King Ethelred the Unready of England and Queen Emma of Normandy and the sister of King Edward the Confessor. Their sons were Waller (Gautier) III, Count of the Vexin, and Ralph the Timid, earl of Hereford.  - Emma of Normandy (c. 985  6 March 1052) was a queen consort of England, Denmark and Norway. She was the daughter of Richard I, Duke of Normandy, and his second wife, Gunnora. Through her marriages to Æthelred the Unready (1002-1016) and Cnut the Great (1017-1035), she became the Queen Consort of England, Denmark, and Norway. She was the mother of three sons, Edward the Confessor, Alfred, and Harthacnut, as well as two daughters, Goda of England, and Gunhilda of Denmark. Even after her husbands' deaths Emma remained in the public eye, and continued to participate actively in politics. She is the central figure within the "Encomium Emmae Reginae", a critical source for the history of early 11th-century English politics. As Catherine Karkov notes, Emma is one of the most visually represented early medieval queens.  - Æthelred the Unready, or Æthelred II (Old English: Æþelræd), ( 966  23 April 1016) was King of the English (9781013 and 10141016). He was the son of King Edgar the Peaceful and Queen Ælfthryth and was around 12 years old when his half-brother Edward the Martyr was murdered on 18 March 978. Although Æthelred was not personally suspected of participation, the murder was committed at Corfe Castle by his attendants, making it more difficult for the new king to rally the nation against the military raids by Danes, especially as the legend of St Edward the Martyr grew.    Given the paragraphs above, decide what entity has the relation 'mother' with 'goda of england'.
The answer to this question is:
ralph the timid
