A review was made of existing genetic genealogy findings that infer characteristics of the Y-DNA of members of the British Monarchy. Nine sustained Y-DNA lineages since the year 927 CE were noted as dynastic groups. Haplogroup and haplotype characteristics of three of the dynasties were presented with two more dynasties noted as testable but unpublished. Cultural and geographical origins of these dynasties were considered as context for their DNA haplogroups. Specimen candidates for further testing were identified noting that some will require Ancient DNA (aDNA) recovery and analysis.
Genetic genealogy using Y-DNA focuses on the portion of the Y-chromosome which passes from father to son with only rare mutations. While many think of the throne of the British monarchy being passed in the same way, that crown has undergone some 'non-linear' transitions over its long history. Counting those transitions which yielded adult heirs to the throne, there have been nine (9) different Y-DNA dynasties in the 1,086 years since Aethelstan became the first King of England in 927 CE.
King William III of Orange (1650-1702), husband of Queen Mary II (1662-1694) King Philip II of Spain (1527-1598), husband of Queen Mary I (1516-1558) King Stephen of Blois (1092-1154)
Mountbatten, Windsor, Hannover, and Stuart dynasties with their monarchs and major patriarchs
Media observers refer to the current royal family as 'The House of Windsor' but the three generations of current royal heirs will probably be known in the future as the Mountbatten dynasty:
Charles, Prince of Wales and heir apparent (b. 1948) Prince William, Duke of Cambridge (b. 1982) Prince George of Cambridge (b. 2013)
All these Mountbatten heirs trace their Y-DNA from Prince Philip Mountbatten, Duke of Edinburgh (b. 1921 Greece). Prince Philip descends maternally from Queen Victoria (1819-1901) and Prince Louis of Battenberg (1854-1921). Phillip's Y-DNA lineage, however, is traced to King Christian III of Denmark (1503-1559) and further back to the medieval House of Oldenburg: John II of Oldenburg, Germany (1272-1301).
the current King Harald V of Norway (b. 1937) the current Queen Margarethe II of Denmark (b. 1940) Prince George Oldenburg of Denmark (1653-1708), husband of British Queen Anne (1665-1714) Nicholas II of Russia (1868-1918), the last Romanov Tsar
Because Prince Philip is also a matrilineal cousin to Tsar Nicholas II's wife, he should have both Y-DNA and MtDNA matches for members of the last Tsar's family. When remains thought to belong to that family were discovered in Russia, Philip personally contributed a DNA sample which helped verify their authenticity.
Both Tsar Nicholas II and Prince Philip, Duke of Edinburgh were paternally descended from Frederik I, King of Denmark and Norway 1523-1533.
Figure 2 illustrates how Prince Philip, Duke of Edinburgh and Tsar Nicholas II of Russia are patrilineal 11th cousins, once removed with a known TMRCA of 450 years.
Based on the Y-STR results released in the Romanov studies, the Mountbatten Y-DNA signature can be inferred from the Tsar's results shown in Figure 3.

The Windsor dynasty began with the crowning of King Edward VII (1841-1910) in 1901 and culminates with its fifth monarch, the current Queen Elizabeth II (b. 1926). The family surname was changed from 'Saxe-Coburg and Gotha' to 'Windsor' when King George V (1865-1936) renounced his Germany territories and titles during World War I. This Y-DNA lineage came from Prince Albert of Saxe-Coburg and Gotha (1819-1861) who was the husband of Queen Victoria (1819-1901). The paternal Windsor DNA line continues back to Franz Josias (Germany 1697-1764); John, Elector of Saxony (1468-1532); and further to Dietrich I of Wettin, Germany (916-976).

The Hannoverians are best known to Americans for King George III (1738-1820) on whom much of the Declaration of Independence (1776) was focused. This lineage came to the throne when Parliament searched far and wide for a new monarch based on religious preference. They found a German-speaking grandson of King James I (1566-1625) through two maternal lines who was dubbed King George I (1660-1727). This dynasty put five (5) members on the throne and traces back to George of Brunswick, Germany (1582-1641).
There is not a Y-DNA signature publically identified for the Hannoverian lineage. However, there are a number of living persons whose genealogies link them to this lineage. For instance, the living male descendants of Ernst August von Hannover (1914-1987) are good candidates for testing.

The Stuart line of monarchs were among the most controversial in their own time. Although their matriarch, Mary Queen of Scots (1542-1567), was beheaded, her son King James I (1566-1625) unified the Scottish and English crowns in 1603. Despite the English Civil War and a twelve-year interregnum, a total of six (6) monarchs were crowned from the paternity of Henry Stuart, Lord Darnley of Scotland (1545-1567). This Y-DNA linage can be traced further back to Robert II of Scotland (1316-1390), Walter FitzAlan (1106-1177) and Alan FitzFlaad (1070-1114) who came from Brittany, France as a knight in Norman service. Because Brittany was settled (and named) by displaced Celts from Britain in the 5th century, this lineage is thought to be anciently Celtic.
Although the Stuart line of British monarchs ended with the death of Queen Anne in 1714, there are several living Dukes and other Peers who are patrilinealy descended from King Charles II (1630-1685).

Tudor and Plantagenet dynasties with their monarchs and major patriarchs
The Tudors are best known for King Henry VIII (1491-1547) and his daughter, Queen Elizabeth I (1533-1603). This dynasty provided five (5) English monarchs and is the only royal male line attributed to Celtic Wales. Henry VIII's father, Henry Tudor (1457-1509), began the dynasty in 1485 by winning the crown in battle for the Lancastrians and closing the War of the Roses by marrying Elizabeth of York (1465-1503). Henry Tudor's paternal ancestors are believed to descend from Ednyfed Fychan (1170-1246) of Wales.
A Tudor Y-DNA signature has not been identified and there are no documented descendants after the 17th century. If a signature can be identified, however, there may be numerous living matches because the 'Tudor' surname is still common where the royal Tudors originated on the Isle of Angelsey in Wales. There is at least one person of Welsh descent and surname who claims paternal descent from Henry VIII's ancestor, Ednyfed Fychan. It is also reputed that Mary Boleyn's first son, Henry Carey (1526-1596), was an illegitimate son of Henry VIII and may have had descendants that survived but faded from historical records. Carey's remains lie in Westminster Abbey while Henry VIII's remains lie in St George's Chapel at Windsor Castle so the potential for aDNA to reveal this Y-DNA signature is tantalizing.
The Plantagenets are perhaps best known for King Edward I [Longshanks] (1239-1307) as portrayed in the movie
Plantagenet DNA characterization has been in the news this past year with an announcement of findings (without data) that MtDNA evidence supports the identification of a body discovered in Leicestershire as being the remains King Richard III (1452-1485).
There have also been news stories about an Australian man named Simon Abney-Hastings, 15th Earl of Loudun (b. 1972), who might have been heir to the British crown from George Plantagent, Duke of Clarence (1449-1478) under an alternative succession.
If a confirming Plantagenet aDNA sample is needed, investigators might consider King Henry III (1312-1377) who was interred in a chest tomb inside Westminster Abbey, London.
Blois, Norman, Wessex, and Knýtlinga dynasties with their monarchs and major patriarchs
The House of Normandy was seated with the successful invasion of England in 1066 by William I [the Conqueror] (1028-1087). This dynasty introduced French language and martial skills into the Anglo-Saxon culture of England. To put it in modern terms, these Normans were the high tech gurus of the 11th century with innovations like the Domesday Book, elaborate castles, and combined-arms warfare. Yet for all the territorial gains of William the Conqueror, his dynasty did not last long - only three (3) monarchs over 69 years. William's Y-DNA came from his Viking ancestor Robert I [Rollo] (846-931) who was probably born in Denmark and became Duke of Normandy, France in about the year 900.
There are no patrilineal descendants of William the Conqueror who survived past the 12th century.
Aethelstan (893-939) was the first person since Roman times to unify all of England under one king in the year 927. While it is common today to refer to persons from the British Isles as 'Anglo-Saxons', it has actually been 947 years since the last true Anglo-Saxon king, Harold Godwinson (1022-1066), was defeated by William the Conqueror. From Aethelstan to Godwinson, the 'West Saxon' or Wessex dynasty provided a total of ten (10) rulers from the Y-DNA lineage of Egbert, King of Wessex (770 - 839) who was born in what is today Oxfordshire, England. Today's English language derives principally from Wessex ancestors who came to Britain from northern Germany between the 4th and 8th centuries.
Although Harold Godwinson perished, there were likely fourteen (14) or more sons or nephews carrying the Godwinson Y-DNA living in the year 1081. However, these individuals receded from history and we simply don't know how to identify any Wessex Y-DNA carriers from traditional genealogy. Since Harold's body is believed to be buried near the battlefield of Hastings, aDNA may yet enable comparison of the Wessex dynasty with living individuals who have been tested. Bones of earlier Wessex Kings are claimed to be inside Winchester Cathedral as well. There is also a new effort to examine remains that might belong to King Alfred the Great (849-899) at Hyde Abbey, Winchester.
Viking forces operated in England from 793 to 1075 with frequent battles against the House of Wessex. A Viking-based dynasty called Knýtlinga was established in 1013 and is best known for King Canute (985-1035) who subdued the Anglo-Saxons; coined his own money; and also ruled over Denmark, Norway, and parts of Sweden. However, Canute's sons all died within seven years of their father so that power in England was reclaimed by the Anglo-Saxons of Wessex.
Canute's Y-DNA line came from Harthacnu I, King of Denmark (880-936). Although Harthacnu I's descendants continued to serve as members of Scandanavian royal families, as far as we can tell, this Y-DNA line
In the past 1,086 years since Aethelstan became the first King of England, there have been nine (9) sustained Y-DNA dynasties. Three (3) of these lineages have publically available Y-DNA characterizations that anyone can compare themselves to with a commercial genetic genealogy test. Two (2) of the royal dynasties have living Y-DNA descendants but test results have not been published. The remaining four (4) lineages are unlikely to have genealogically-identifiable living descendants. Thus aDNA testing of royal remains will be needed in order to identify their characteristics and draw new genealogical and historical insights.
Geographically, only one (1) of these dynasties (Wessex) originates in England before the 10th century and another in Wales. Six (6) of these dynasties converge on Germany and Denmark (and Wessex would make a seventh if one considers its origins prior to the 7th century). Two (2) more of the dynasties originate in France. Culturally, two (2) of these dynasties are Celtic in origin, two (2) French, and five (5) Germanic.
Nine Y-DNA dynasties have produced adult heirs to the British throne since the first King of England in 927 CE.
