Recently I have been reflecting on the latest y-dna charts of R1b L21 of which R1b M222 belongs and the Davidic genealogies which I have been researching and studying for nearly 40 years. Different studies led me to the conclusion that Joseph of Arimathea or his son may have been the founder as well as ancestor of M222 rather than High King Niall of the Nine Hostages of Ireland. However as further research has progressed I think that the original idea that M222 began with Niall or his father or grandfather to be closer to the truth. It is from Niall's ancestor Nuadh or Nathan (Nahori) the Fisher Lord of Glastonbury (b.115 AD d. 171 AD) the son of Rabbi Meir that M222 seems to originate. His son went to Ireland and was known as Mar Eoghan (Ugaine Mor/Johannan/Angus Og) King of Munster and was the founder of the Irish M222 clan and was the ancestor of Niall of the Nine Hostages. The Southern English branch of M222 came from Nuadh's sons who remained in Britain.
St Joseph of Arimathea is the ancestor of R1b L21 DF13 Z39589 y-dna. St Joseph of Arimathea is also the ancestor of those who descend from M222 but he belongs to R1b L21 which is the ydna of the Davidic House of Nathan. St Joseph of Arimathea was the British Jewish Christian Nasi or Exilarch (Rosh Golus) at Glastonbury in Somerset. Niall is a male line descendant of Joseph's great grandson Zerah (Adon Glas) the Lord of Glastonbury (the Glas or Golus Isle) the son of Nathan the Red (Nectan Ruadh/Nuadh Nect) who lived from 30 -90 AD who is recorded as an Irish High King (Ard Ri) but was in reality the Jewish Christian Nasi or Exilarch known as a Rosh Golus (Head of the Exile) or Dayag Adon (Fisher Lord) of Ireland (Erani/ Hibernia). It is thus likely that R1b L21 DF13 DF49 (ancestral or upstream of M222) began with Zerah Adon Glas of what would one day be southern England (south-west Britain). DF 23 may be the branch of L21 descended from Rabbi Meir (Meir Duach/Raibh Dearg) the Dagda (Dayag Adon/Fisher Lord) [b.99 d.162] and famous Rabbi related to Nero. He was not the grandson of Nero as told in Jewish legend but it was his great grandmother Julia Nero that belonged to the same Nero family as the Emperor Nero.
The Royal House of Stuart are also descendants of St Joseph of Arimathea. Through the Dukes and Lords of Brittany the Stuarts trace back to Gabhran the Ruler of Dal Riata and all Britain and Brittany through his great-grandson Hoel Mawr Duke of Brittany. Gabhran or Gadeon was the son of a Jewish British Prince Huna Mar (Cunomor) who became a Babylonian Exilarch in the 6th century. Gabhran's great-grandson Hoel Mawr (son of Eochaidh Buidhe King of Dal Riata the son of King Aedan) was the founder of R1b L21 DF13 CTS658/DF41. All the later Babylonian Exilarchs descend from Huna Mar through Gabhran's brother the famous King Arthur Mor who was King at first of the Pennines and Goddodin before becoming the great British King Emperor.
King Aedan of Dal Riata and High King of Britain's grandson Domnall or Donald Brecc King of Dalriata is most likely the ancestor of R1b L21 L1335 ydna. Through Aedan's son King Eochaidh Buidhe of the Dal Riata Scots descends King Alpin of the Picts the father of Kenneth I Mac Alpin King of Scots and Picts. The MacKinnon and Buchanan Clan founders descend from the two sons of Constantine III (Kyan/ Kinnon) King of Scots (Alba) Anselan O Kyan and Findanus MacKinnon. The Welsh branch of L371 of R1b L21 may descend from King Aedan's son Arthur who was also a King of Gwent as well as a Dal Riatan Prince. This Dal Riatan Arthur and King Arthur Mor have been confused in the legendary tales of King Arthur.
Arthur Mor or his son or grandson was probably the founder of R1b L21 DF13 S470/Z251. It is from King Arthur Mor that the later Babylonian Exilarchs and the Jewish Kings of Septimania in France descend on the direct male line. The Danish Royal House of Oldenburgh descends from him via the Exilarch family that went to Barcelona in the 10th century. The Norman Kings of England descend from Machir Theodoric the Jewish King of Narbonne through his eldest son Mar Menachem who was also known as Hernaut and Harald who married the Danish heiress Hilda. These lines also trace back to Nathan the Red of Ireland through his other son Mar Phares of Caledonia who was the first Jewish Christian Nasi or Exilarch (Guleta/ Guletic) of Scotland (Scotti/ Caledonia/ Alba). The Carolingian Kings and Charlemagne are also direct male line descendants of Mar Phares via Angus (Anlach/ St Brychan/ Banlach/ Ban) King of Breicheiniog in Wales the brother of Huna Mar and father of Lancelot. The Welf or Guelf family of Queen Victoria also descends from the Jewish Exilarchic family in Barcelona in the 10th century. Both the House of Oldenburgh and the House of Welf-Este descend from Mar Barzilay of Barcelona on the direct male line. The Spanish Kings of Castile, Aragon and Leon descend from Machir Theodoric the Jewish King of Narbonne through the Counts of Burgundy from his eldest son Mar Menachem (Harald Hildetonn/ Hernaut de Gironde).The Carolingian Kings may be of the Z16500 branch of R1b L21 ydna. The Anglo-Saxon Kings of Kent and Wessex descend from Athelbert King of Kent (d.616) a grandson of King Arthur Mor.
Z16246 comes from the DF 63 branch of Milesian R1b L21 ydna haplogroup. They are a Milesian male line group. It is likely that DF63 are descendants of Breoghan or Brennius who led the combined Gaelic and Celtic forces against the Greeks in the Balkans around 280 BC. It would seem to me that DF63, from which Z16246 descends, is from a son or grandson of Breoghan (Brennius) who remained in Europe as the leader of a contingent of Milesians that allied with the European Kelts while the other Milesians invaded Ireland and Britain.
FGC11134 haplogroup of R1b L21 is the branch of the Milesians descended from Heber who invaded Ireland with Heremon and settled in the south of Ireland. DF1/L513 is most likely the haplogroup of the Milesians descended from Heremon who invaded Ireland with Heber. ZZ10 is most likely the clan of Ir of the Milesians. The socalled Dalcassians are probably descended from Conmac the son of Fergus MacRoy King of Ulster who has been confused with Cormac Cas the son of Oiliol Olum the King of Munster in the Irish genealogies. Conmac and Fergus descend from Olum Fodla and Ir.
DF 21 haplogroup are most likely the descendants of St Joseph of Arimathea's brother Nathan ben Eli (Nascien/ Tenaufan/ Tasciovanus) King of the Regnoi and Catevaullani. He is the ancestor of many of the early British Kings. FGC5494 may be the descendants of the Beredi or Breoghanites who settled in Britain when the others invaded Ireland.
