Richard of York was born about 20 July 1385 at
Conisbrough Castle, Yorkshire, the second son of Edmund of Langley, 1st Duke of York, and his first wife,
Isabella of Castile. On his father's side, he was the grandson of
King Edward III and
Philippa of Hainault, and on his mother's side, the grandson of
Peter the Cruel, King of
Castile and
León, and his favourite mistress,
María de Padilla (died 1361). There is no record of his birth or baptism, and some put his birth in about 1375. His godfather was
King Richard II, a fact that argues for the later date. Richard II was at York on 20 July 1385, close enough to serve as godfather to the future Earl of Cambridge, while in 1375 the future king was only eight years old; it was unlikely he would have been a godfather at that age, and with his father still alive. Richard was twelve years younger than his brother,
Edward. Strangely, Richard received no lands from his father and was mentioned neither in his father's will nor his brother's will. This circumstance has been taken by
G.L. Harriss as an indication that Richard's father and brother did not recognize him as a full blood relative, and that he may have been the child of an illicit liaison between his mother and the king's half-brother
John Holland. This theory gained new life following the DNA studies of the remains of Richard III in 2014. Although Edmund of Langley made no provision for Richard in his will of 25 November 1400, his mother Isabella named King Richard II as her heir before her death on 23 December 1392 and requested him to grant her younger son an annuity of 500 marks. The king complied. On 3 February 1393, he provided his godson with an annuity of £100 from the revenues in Yorkshire that Isabella had formerly received, and on 16 March 1393, he provided him with a further annuity of 350 marks (£233 6s 8d) from the
Exchequer. According to T. B. Pugh, further largess from the king might have been expected when Richard came of age; however, Richard II was deposed in 1399. According to G. L. Harriss, Richard of York "received no favours from the new King,
Henry IV". After Henry IV's accession, Richard's annuities, his sole source of income, were either paid irregularly, or not paid at all. From April 1403 to October 1404, Richard commanded a small force defending
Herefordshire against the Welsh rebel leader
Owain Glyndŵr, but otherwise performed no notable military service. However, it was during this period, according to T. B. Pugh, that Richard established the relationships with the Mortimer and Cherleton families that brought about his marriage to
Anne de Mortimer. Richard's only other significant appointment during this period came in August 1406 when, together with the
Bishop of Bath,
Lord FitzHugh, and
Lord Scrope, he was chosen to escort
King Henry's daughter
Philippa to Denmark for her marriage to
King Eric. Richard was knighted in July of that year, perhaps in anticipation of this embassy. Pugh notes that during this three-month embassy to Denmark, Richard would have become well acquainted with
Lord Scrope, who married Richard's stepmother
Joan Holland in September 1411, and with whom Richard later became involved in the
Southampton Plot of 1415 that cost them both their lives. ==Southampton Plot==
