Oengus I MacFergusa b.670 d.761 left the North American Kingdom of Appelachia and Alleghania around 710 AD after the death of his father Donaldus II with two of his brothers Talorcus (Talorgan) and Brutus (Brudei). He was a younger brother of Donaldus III and went to claim the inheritance of his mother Fergusa of the small kingdom or principality of Circin in Scotland. He was at first known as the Angus of Circin and eventually Circin became known as Angus and the ruler was called a Mormaer of Angus. 

Oengus had arrived in Scotland in the reign of Nectan or Nathan III King of Picts. He was welcomed by Nectan as the heir to the Throne of Angus. The Pictish King Nectan or Nathan III (r.706-724) abdicated the Pictish throne in 724 to enter a monastery. He was suceeded by King Drest VII who in 726 imprisoned him. This caused four Pictish Kings to clash and Oengus supported Nectan and Alpin supported Drest at first. However, Alpin soon turned on Drest and expelled him from the Kingdom and became the paramount Pictish King as Alpin I himself for two years when Oengus succeeded in overthrowing him by killing him in Battle and placing Nectan back on the Throne. It would seem that Alpin whose name is a variant of Aleph was a Jewish King of the Picts whereas Nectan and Oengus were Judeo-Christian Kings.

Angus was thus a great Warrior leader and eventually became the King of the Picts in 732. He appointed his brother Talorgan I as the Angus of Circin in 736. Talorgan died in 750 and was succeeded by his brother Brudei I as the Angus of Circin. On the death of Oengus I macFergusa he was succeeded his brother as Brudei V as King of Picts in 761.  Oengus' son Talorgan II b.715 succeeded his uncle as the Angus of Circin or Mormaer of Angus in 763. 

Oengus was associated with St Andrew as the emblem of the House of Angus in North America was the yellow flower shaped like a St Andrew Cross. The Pictish lands were divided into seven sub-kingdoms Cait (Caithness and Sunderland), Ce (Mar and Buchan), Circin (Angus and Mearns), Fib (Fife), Fidach (Inverness), Fotla (Atholl) and Fortriu (Moray). After the arrival of the Khazars in Scotland in 969 the areas of Moray, Angus and Atholl came under their sway. However it would seem that the remnants of the House of Oengus allied themselves and intermarried with the Khazar Royal House.

Oengus also had a son called Brudei b.713 who died in 736 who was a noted Warrior.  Oengus' daughter Princess Ferat b.720 (Ferat V of Atholl) married Fiachnae the King of Ulaid. Talgoran II became the king of Picts in 778  and his son Drest b.742 became the Angus and when his father died in 782 he then became Drest VIII as King of the Picts. When Drest became King of Picts in 782 he was succeeded as Angus by his brother Talorgan III (Talorc). Talorgan III in 783 on the death of his brother became the King of Picts. Talorgan III was succeeded in 783 as the Angus by his relative Constantine who was the son of Princess Fergusa b.741 a daughter of Queen Ferat of Ulaid. 

Princess Fergusa was the wife of Eochaidh IV of Scots Dalraida and Ulaid. Their son Constantine b.760 became the Angus in 783 and the King of Picts  in 789 on the death of King Conall of Picts (r.785-789) the son of Princess Tagh (Tegan or Tegana) I of Picts and Eochaidh II the King of Scots Dalriata. In 789 Constantine's brother Oengus II Mac Fergusa b.762 became the Mormaer of Angus (the Angus of Circin) and the King of Picts in 820 on the death of his brother Constantine. 

Oengus II married Princess Tagh II the daughter of Alpin II King of Picts and Princess Ferat (Ferat VI of Atholl) of the Midi in Ireland. In 820 Oengus II was succeeded as the Angus by his nephew Drest II who in 834 on the death of Oengus II became Drest IX King of Picts. Drest IX remained as the Angus and reigned as a joint -King with his cousin Talorgan IV of Atholl who was a son of the Queen Ferat VII of Atholl who was a sister of Oengus II Mac Fergusa. Drest reigned over the northern Picts and Talorgan over the southern Picts. When they both died in 837 they were succeeded as Angus and King of Picts by Eoghan the son of Oengus II who reigned from 837 to 839 when he was killed in battle against the Vikings. 

Around 875 Eugenius the last Angus of Appelachia and Alleghania in North America fled to Scotland and became the ruler of Angus or Circin in Scotland and married a daughter of Prince Indrechtaig mac Donchadha of the Royal Family of the Midi (Cavan) and Princess Gobnait of the Scots and Picts. Princess Gobnait was a daughter of King Kenneth MacAlpin of the Scots and Picts and his wife Princess Bride of the Picts a daughter of Brudei VI of Picts (r.842-843). Brudei VI was a son of Uurad of Atholl who was a son of Talorgan IV and Princess Ferat IV of Picts b.780 (Ferat VIII of Atholl). Uurad married Princess Ferat VI of Angus and Picts b.803 (Ferat IX of Atholl) a daughter of Oengus II. 

Uurad was the King of Picts from 839-842 and was succeeded by his brother Ciniod II briefly in 843. Ciniod was succeeded by his cousin Brudei VII who was a son of Uurad's sister Princess Fodela of Atholl and he reigned as King of Picts from 843-845. In 845 another son of Uurad became King of Picts as Drest X and competed with Kenneth MacAlpin for the throne of the Picts.

Around 910 Eugenius' son Dubacan became the Mormaer of Angus  and around 937 he was succeeded by his son Dubh MacDubacan as the Mormaer of Angus and his son Duncan was the Thane of Dull and another son was Dubdon the Mormaer of Atholl. Dubh macDubacan's descendants are R-FT387578 y-dna. The later Mormaers of Angus were only descended on the maternal line from the House of Oengus but were Khazars of R1a y-dna on the male line descended from Joseph III the Khazar King in Scotland who was also known as Cellach and Cuncar (short for Khagan of the Khazars). 

The name Ferat among the Picts was derived as a title for a female Pharaoh. These Queens had their own Queendom of Atholl. Due to the Vikings and the chaos this insured the history of these queens has been forgotten and can only be restored to the light by studying the traces still evident in the legends, genealogies and histories of Scotland and Ireland. They believed in the legend that their ancestress was a daughter of Pharaoh and it was only men who had a Royal Pictish mother that could inherit the throne of the Pictish Kingdom.

Ferat I (r.655-675) was a Jewish Princess of Bernicia and the Picts. Her father was Eanfrith the King of Bernicia b.590 d.634 and her mother Bega or Rebecca a Royal Pictish Princess and a Princess of Munster (Mumhan) in Ireland. She moved to North America to marry Bice the Ruling Prince of Ragheallchia. She was born in 614 and she returned to Britain after the death of her husband in 655 and at the age of 41 became the ruler of Atholl under the title of Ferat.

Ferat II (r.675-680) was the sister of Ferat I who was born in 615 and married Drest VI King of Picts d.672. 

Ferat III (r.680-701) was the daughter of Ferat II who was born in 632. She married Lord or Prince Crup b.630 a Pictish noble who was a son of King Brudei or Bridei III King of Picts b.612 d.693 and Princess Edwina of Deira the daughter of King Edwin of Deira b.586 d.633 and Bernicia and Princess Alpina or Elfina of Strathclyde b.594.

Ferat IV (r.701-735) was a granddaughter of Ferat III who was born in 672. She was the daughter of Princess Fergusa b.652 who was the sister of King Alpin I King of Picts b.650 and wife of Finguine mac Cathail, King of Munster. She married Oengus I MacFergusa whose mother was a sister of Ferat II. 

Ferat V (r.735-784) who was the daughter of Ferat IV who was born around 720. She married Fiachnae the King of Ulaid in Ireland.

Ferat VI (r.784-810) who was a maternal descendant of Ferat III through her daughter Fergusa b.652. She was born in 741. she was the daughter of Princess Fuirseach of Dal Riata b.708 and King Donnchadh Midi the King of the Midi in Ireland. She married Alpin II King of Picts who was of a Jewish branch of the Pictish Royal House.

Ferat VII (r.810-840) who was the daughter of Ferat VI. She was born in 761. She married Ciniod II King of Picts, though he only became the King of Picts after her death.

Ferat VIII (r.840-864) who was a daughter of Ferat VII. She was born in 780. She married Alpin III King of Picts and Dal Riata and was the mother of Kenneth MacAlpin King of Scots.

Ferat IX (r.864-875) who was a granddaughter of Ferat VI. She was born in 803. She was the daughter of Princess Tadg II of Picts and her husband Oengus II MacFergusa. 

The name of Tadg, Tegan, Tegana, Tiarna and Teigan come into the Pictish Royal House from the Fairy Queens of Cork who were the rulers of the ancient Kingdom of Iterni (aka Tír Tairngire) which was once on the coast of Cork in the 2nd century but later moved inland to the area around Lissacresig Ringfort, Fairyland, Carrigaphooca Stone Circle and Carrigcleena. These Queens descend from the "Fairy" Queen Cliodhna (pronounced Kli-un-a or Kleena) and her son Teige or Tadgh. This is the origins for the names of Puc and Titiana in Shakespeare. 

Edmund Spenser also drew on these legends with his figures of Una, Duessa and Gloriana the Fairy Queen. Una represented the Fair Jewish Queens and Duessa the Dark Jewish Queens. He or at least the people of his time associated Elizabeth I with the figures of Una and Gloriana (the English Queen Regnant and the Anglican Church) and Duessa with Mary Queen of Scots and the Catholic Church. Thus, the title Ferat alluded both to the Fair or Fairy Queen and the Daughter of Pharaoh. If one neglects the rich folkloric, legendary, mythological and genealogical inheritance of our ancestors then one will not perceive this rich hidden history of our ancestors which also seems to surface at times in our great literary figures that have somehow tapped into our hidden history in their fictionalised accounts. this is true of the works of Shakespeare, Spenser, Sir Walter Scott, CS Lewis, Tolkien and others.
