Born: 5 June 1341 at King's Langley Palace in King's Langley, Hertfordshire, England. 
Controversy regarding paternity: A 2014 Y-DNA study compared the DNA of Edward III’s descendants, namely Richard III and 5 men descended from Henry Somerset, 2nd Earl of Worcester.  Richard III descended in the male line from Edward’s son Edmund of Langley, and Henry Somerset descended in the male line from Edward’s son John of Gaunt. The Y-DNA did not match. The press sensationalized the announcement to suggest that Edward III might not be the father of Edmund of Langley or John of Gaunt, or even of his other children. 
However, this is an extremely poor analysis of the data. Certainly, there was a non-paternal event(s) somewhere in the line down to his gr-gr—grandson Richard III, or somewhere in the 24 to 26 generation descent in the Somerset lines. It is not possible to tell where the non-paternal event occurred from this study. At this point, all the children of Philippa of Hainault must be presumed to be the children of Edward III, King of England.

Death and burial of Edmund of Langley
Died: 1 August 1402 at King's Langley, Hertfordshire, England. 
Burial: Church of the Friars Preachers in King's Langley, Hertfordshire, England. 
From: Royal Tombs of Medieval England - "The fifth son of Edward III and Philippa of Hainault, Edmund was born at the royal manor of Langley in 1342 and died there on 1 August 1402. The duke was buried in the nearby priory church (Friars Preachers), as instructed by his will dated two years earlier. King's Langley was a Dominican house founded by Edward II in 1308 in the grounds of the royal manor-house, the result of a vow made when he was in 'great peril', most likely illness. Edward III took control of the building works in 1360, but the priory was still incomplete in 1399. Edmund's wife, Isabella of Castile, had been buried at King's Langley in 1394 on instructions from Richard II; according to Dugdale, Isabella's will left her burial-place to the king's discretion. There are no records of the King's Langley tombs. The priory surrendered to the crown in 1536, but was not dissolved until 1559, when the estate passed into private hands. The heraldic tomb-chest now standing in the north chapel of the King's Langley parish church is thought to have originated from the priory, and is usually ascribed to Edmund Langley, being moved to its present position in 1877. There is no effigy or inscription. The chest was executed in Purbeck marble with alabaster panels. In 1877 the tomb-chest was opened and found to contain the disturbed remains of a male about sixty and a female around forty, thought to be Edmund and Isabella."
