Leonor Rodríguez de Castro
Leonor Rodríguez de Castro( died after 20 December 1275) was an infanta of the Kingdom of Castile as the third wife of Philip of Castile.
Inge the Younger
Inge the Younger was King of Sweden in c. 1110–c.
1125 and the son of king Halsten
and he was probably Halsten's youngest son.
According to unreliable traditions Inge would have ruled together with his brother Philip Halstensson after the death of their uncle Inge the Elder: In English literature both have also been called "Ingold".
Hallstein's sons were Philip and Ingi, and they succeeded to the Kingdom of Sweden after King Ingi the elder.
(The 13th century "Hervarar saga")
Other sources say that after the death of Philip (1118), Inge the Younger was the sole king of Sweden, but the year of his own death is unknown.
According to the regnal list in the "Westrogothic law", Inge was poisoned with an evil drink in Östergötland:
Niunði war Ingi konongær, broðher Philipusær konongs,
oc heter æptir Ingæ kononge, Halstens konongs brødhær.
Hanum war firigiort
mæð ondom dryk
i Østrægøtlanði, oc fek aff þy banæ.
Æn Sweriki for e wæl, mædhæn þer frænlingær rædhu.
The tenth (Christian king) was king Inge, the brother of king Philip, and he was named after king Inge (the Elder).
He was killed by evil drink in Östergötland
and it was his bane.
But Sweden fared forever well, while these kinsmen ruled.
It is not known whether Inge was still alive when the Norwegian king Sigurd I of Norway invaded Småland in 1123, but when Inge died, it was the end of the House of Stenkil.
Inge is reported to have been married to Ulvhild Håkansdotter who was the daughter of the Norwegian Haakon Finnsson and who would later marry the Danish king Nils Svensson and even later the Swedish king Sverker the Elder.
A story that has her assassinating King Inge with a poisoned beverage cannot be substantiated.
According to another tradition, he was also the husband of Ragnhild of Tälje.
Philip of Sweden
Philip or Filip  was King of Sweden from c. 1105–1110 until 1118.
He was a son of King Halsten Stenkilsson and nephew of King Inge the Elder.
Philip and his brother Inge the Younger ruled together from 1105 or 1110 and onwards as successors of their uncle King Inge the Elder.
According to the records of the Westrogothic law ("Västgötalagen") he was a good king.
Little else is known about him.
Hardly any other Swedish king who was the undisputed ruler of the kingdom after the Christianization is less known than Philip.
According to the "Hervarar saga", he ruled only for a short time and was married to Ingegard, the daughter of the Norwegian king Harald Hardrada.
Philip was probably buried with his brother Inge the Younger in Vreta Abbey ("Vreta kloster och kyrka") at Linköping in Östergötland, Sweden.
