Question: Princess Astrid, Mrs. Ferner is the older sister of a king who ascended to the throne on which day ?
Context: Somdet Phra Ramesuan (Thai: สมเด็จพระราเมศวร ) (1339–1395), son of king Ramathibodi I, reigned as the second and fifth king of the kingdom of Ayutthaya.  When King Ramathibodi ascended to the throne of Ayuthaya, he sent King Ramesuan to reign in Lavo.  Upon King Ramathibodi's death in 1369, King Ramesuan traveled to Ayutthaya to assume the throne, but held it for less than a year before being deposed by his uncle, King Borommaracha I, the ruler of Suphanburi.  Sources differ over the nature of their conflict; official chronicles state that the older Boromaracha ruled with the willing consent of his nephew, while Jeremias van Vliet's "Short History of Thailand" indicated that Boromaracha's ascension came only after a bloody conflict bordering on civil war. Princess Astrid, Mrs. Ferner (Astrid Maud Ingeborg; born 12 February 1932 in Oslo, Norway) is the second daughter of King Olav V of Norway and his wife, Princess Märtha of Sweden.

Sen Soulintha, Saen Surintha or Sen Sourintha (1511–1582) was born Chane Tian and became King of Lan Xang reigning 1571-1575 and again 1580-1582.  Sen Soulintha was not of noble birth, rising from royal page to King Setthatirath’s Chief Minister.  During the succession disputes in the Kingdom of Lan Na between King Setthatirath and King Mekuti, Sen Soulintha served Setthatirath as a general and successfully took several cities of Lan Na including Chiang Saen for which he was given the honorific name "Lusai" meaning “victory.”  Sen Soulintha supported Setthatirath in leading the guerrilla campaigns during the Burmese invasions of King Bayinnaung.  When Setthatirath died near Attapeu under suspicious circumstances in 1572, Sen Soulintha led the armies of Lan Xang back to Vientiane.  A succession dispute erupted, which nearly led to civil war and provided a pretext for another Burmese invasion ordered by Bayinnaung and led by the Chief Minister Binnya Dala.  Sen Soulintha defeated the Burmese and Lan Na forces led by Binnya Dala, an event which led to the latter’s exile, only to face a more massive invasion led by Bayinnaug the following year.  Sen Soulintha again attempted to resort to guerilla tactics, but lacked popular support from his seizure of the throne.  He and his son Ong Lo (Nakhon Noi) were captured by Bayinnaung and exiled to Pegu.  The Burmese placed Setthathirath’s brother, and former "Ouphahat" or Viceroy, Prince Tha Heua on the throne.  According to the Luang Prabang chronicles it was this brother, who had led a rebellion in Luang Prabang and tried to seize the throne from Setthathirath on the death of their father Photisarath.  Prince Tha Heua took the regnal name Voravongsa and reigned under Burmese suzerainty from 1575-1579.  Voravongsa was never popular, and drowned with his family while attempting to flee Vientiane in the face of popular uprising.  In 1579, Bayinnaung dispatched a sizable army to restore order.  According to Lao histories Sen Soulintha was then installed as king a second time in 1580.  By that time Sen Soulintha was an old man and reigned only for two years before his son ascended the throne as Nakhon Noi and another succession dispute ensued.
