Philip of Cognac
Philip of Cognac (early 1180s – after 1201) was an illegitimate son of Richard the Lionheart, King of England, by an unidentified mother.
Philip had reached adulthood by the end of the 1190s.
His father married him to his ward, Amelia, the heiress of Cognac, France, in Charente.
However, when she died without issue, Richard kept the castle, and handed it over to his seneschal, Robert of Thornham.
The king was mortally wounded during the suppression of a revolt by Viscount Aimar V of Limoges in 1199, and died without legitimate heirs.
The chronicler Roger of Howden claimed that later that same year,
No other source corroborates this, or explicitly indicates that Aimar of Limoges's death was a violent one.
However, Guiraut de Bornelh's "planh" (lament) for him, "Planc e sospir", does suggest his death was unexpected.
A further reference to Philip is found in the "Pipe Rolls" for 1201 of his uncle, John, King of England:
Et Philippo
f. R. Ricardi 1 m. de dono R.
(And to Philip, son of King Richard, one mark as a gift), but nothing later.
It seems likely that he died early in the 13th century.
It is written in this Wikipedia
he died with no issue
but online sources mention
he had a daughter Aumus of Cognac with link attached of her marriage to D’Orthe family.
There are descendants of her marriage living at present.

Richard I of England
Richard I (8 September 1157 – 6 April 1199) was King of England from 1189 until his death.
He also ruled as Duke of Normandy, Aquitaine and Gascony, Lord of Cyprus, Count of Poitiers, Anjou, Maine, and Nantes, and was overlord of Brittany at various times during the same period.
He was the third of five sons of King Henry II of England and Duchess Eleanor of Aquitaine and seemed unlikely to become king, but all of his brothers except the youngest, John, predeceased their father.
Richard was known as or Richard the Lionheart because of his reputation as a great military leader and warrior.
He was also known in , because of his reputation for terseness.
By the age of 16, Richard had taken command of his own army, putting down rebellions in Poitou against his father.
Richard was a central Christian commander during the Third Crusade, leading the campaign after the departure of Philip II of France and achieving considerable victories against his Muslim counterpart, Saladin, although he did not retake Jerusalem from Saladin.
Richard spoke both French and Occitan.
He was born in England, where he spent his childhood; before becoming king, however, he lived most of his adult life in the Duchy of Aquitaine, in the southwest of France.
Following his accession, he spent very little time, perhaps as little as six months, in England.
Most of his life as king was spent on Crusade, in captivity, or actively defending his lands in France.
Rather than regarding his kingdom as a responsibility requiring his presence as ruler, he has been perceived as preferring to use it merely as a source of revenue to support his armies.
Nevertheless, he was seen as a pious hero by his subjects.
He remains one of the few kings of England remembered more commonly by his epithet than his regnal number, and is an enduring iconic figure both in England and in France.
