Question: Who is Tekle Haymanot Ii's paternal grandfather?

Knowledge 1: Tekle Haymanot II
Tekle Haymanot II (Ge'ez ተክለ ሃይማኖት, "Anchor of the faith"; 1754 – 7 September 1777) was "nəgusä nägäst" as Admas Sagad III (Ge'ez አድማስ ሰገድ "to whom the horizon bows"; 18 October 1769 – 13 April 1777) of Ethiopia, and a member of the Solomonic dynasty.He was the son of Yohannes II by "Woizero" Sancheviyar, at the Imperial prison of Mount Wehni.The Scots explorer James Bruce (who was in Ethiopia from September 1769 to November 1771) described his appearance as follows: [SEP] Knowledge 2: Yohannes II
Yohannes II or John II (Ge'ez ዮሓንስ), (1699 – 18 October 1769) was "nəgusä nägäst" of Ethiopia, and a member of the Solomonic dynasty.He was the son of Iyasu I, and brother of Emperors TekleHaymanot I, Dawit III and Bakaffa.According to James Bruce, during the reign of his brother Bakaffa (1721-1730), the Emperor had vanished from view and a rumor circulated that Bakaffa had died.Qegnazmach Giyorgis acted on this by bringing Yohannes down from the royal prison on Wehni to rule, but before Yohannes could be proclaimed emperor, Bakaffa revealed himself and ordered the two men punished for their presumption, Giyorgis with death and Yohannes by having his hand cut off.However, in his edition of Bruce's work Alexander Murray replaced Bruce's words with a summary of the "Royal Chronicle", which records Yohannes had lost his hand for escaping from Wehni prior to this event, and instead, along with the other royal prisoners of Wehni, had refused to descend and be made Emperor.In either case, Yohannes did not become emperor during the 1720s or 1730s.Then, later, following the murder of Iyoas I in 1769, Ras Mikael Sehul summoned the late Emperor's great-uncle, Yohannes, from Wehni, although Yohannes must then have been in his seventies at least, and presented him to the royal council as his choice for Emperor.When one of the council pointed out that Yohannes lacked one of his hands (it had been cut off in punishment for attempting to escape from Wehni), Mikael replied that if Yohannes needed help mounting his horse, he himself would help Yohannes.Mikael married Yohannes to Mikael's own young granddaughter, Waletta Selassie.Yohannes' reign is succinctly recounted by E. A. Wallis Budge:

Tekle Haymanot I(" Plant of religion," throne name Le`al Sagad," to whom the exalted bows"),( 28 March 1684 – 30 June 1708) was" nəgusä nägäst"( 27 March 1706- 30 June 1708) of Ethiopia, and a member of the Solomonic dynasty.He was the son of Iyasu I and Empress Malakotawit.He is often referred to as" Irgum Tekle Haymanot" or" Tekle Haymanot the Cursed" Tekle Haymanot became Emperor following Iyasus' retirement to an island in Lake Tana.With the support of his mother Empress Malakotawit, some of the officials argued, after the precedent of king Kaleb, that Iyasu had abdicated, and crowned Tekle Haymanot" nəgusä nägäst" in Gondar.This act was not embraced by the entire state, and the resulting civil strife led to Iyasu's murder at the order of his son Tekle Haymanot.In September, 1707, a rebel in Gojjam declared himself" nəgusä nägäst" under the name Amda Seyon, and made his way to the capital city, where he had himself crowned.Tekle Haymanot quickly returned to Gondar, despite the difficulty of travel during the rainy season, forced the usurper to flee, and celebrated his triumph.Amda Seyon was later killed in battle in Maitsa.However his unpopularity for having ordered the murder of his widely revered father was profound and he never overcame it.The involvement of his mother Melekotawit, and the acceptance of his position by other members of the dynasty did irreparable harm to the image of the monarchy.His own courtiers plotted against him, and discussions abounded about whether it was worthy to keep such a corrupt dynasty in power.While travelling in the provinces, Tekle Haymanot was stabbed to death by some of his late father's courtiers.Some historians date the beginning of the Ethiopian Zemene Mesafint or" Era of the Princes"( a time of disorder when the power of the monarchy was eclipsed by the power of local warlords) the murder of Iyasu the Great by his son Tekle Haymanot, and the resultant decline in the prestige of the dynasty.
