Eystein Glumra
Eystein Glumra(" Eystein the Noisy" or" Eystein the Clatterer"; Modern Norwegian" Øystein Glumra") also known as Eystein Ivarsson, was reputedly a petty king on the west coast of Norway, during the 9th Century.
The" Heimskringla" saga states that Eystein Glumra was the father of Rognvald Eysteinsson and Sigurd Eysteinsson:" The first earl in the Orkney Islands was called Sigurd, who was a son of Eystein Glumra, and brother of Ragnvald earl of More.
After Sigurd, his son Guthorm was earl for one year.
After him Torf- Einar, a son of Ragnvald, took the earldom, and was long earl, and was a man of great power".
According to the" Orkneyinga Saga", Eystein Glumra was the son of Ivar the jarl of Uplanders and grandson of Halfdan the Old.
" Orkneyinga Saga" also named Eystein Glumra as the father of Rognvald Eysteinsson:" Heiti, Gorr ’s son, was father of Sveiði the sea-king,[ who was] the father of Halfdan the old,[ who was] the father of Ivar the Uplanders ’ earl,[ who was] the father of Eystein the noisy,[ who was] the father of earl Rognvald the mighty and wise in council".

Suleyman Shah
Suleyman Shah( Modern) was, according to Ottoman tradition, the son of Kaya Alp and the father of Ertuğrul and Gündogdu, who was, in turn, the father of Osman I, the founder of the Ottoman Empire.
However, early Ottoman genealogies did not all agree on this lineage, some failing entirely to mention Suleyman Shah as one of Osman's ancestors.
The connection between Osman I and Suleyman Shah may have been invented at a later date.
His other son was Saru Yatı, the father of Bay Hodja.
It is said that Suleyman Shah drowned in the river Euphrates in Syria.
An Ottoman tomb in or near Qal'at Ja'bar has historically been associated with Suleyman Shah.
