Well, I'm obsessed with this line I've created and so, here's a continuation of
this line and an adaptation of
these infoboxes (I have liberally not shown miscarriages, stillbirths and probably some infant deaths)

Something of the British equivalent to Louis XIV in the sense of the sheer opulence of his court (Whitehall being the closest comparison to OTL Versailles), his reign saw the unification of the British isles under one crown and the heavy focus on expanding British colonies in North America, who by the time of his death had become remarkably feudal in their nature (Maryland, BTW, is ITTL Georgia). During his reign Britain broke its decades-long neutrality in continental matters (Richard I of Belgium was offered his throne, and the Prince-Bishopric of Fulda had been a mercenary), becoming involved on the Iberian War between 1715 and 1723, when Spain, under the prodding of the Pope, invaded Portugal due to its status as a "heretical nation", and was in route to the War of Imperial Succession by the time of his death
*A sort of morganatic marriage that appeared in Britain in specific and was a fad in the early 18th century, it basically means that while united in matrimony by God, the couple is not considered as being so by the laws of the realm, and any child they may have or have had will not be in line to their father's titles

4) Marie Eglantine of Belgium (b.1750:1800)
5) Richard of Belgium, Prince Consort of Quedlimburg (b.1751:1812)
2) Line of James VII & I
Succeeding her father as monarch as European tension rose, her reign was marked by the War of Imperial Succession, as her niece Maria Antonia claimed the position of Holy Roman Emperor for herself after her brother's death without heirs (as by that time the title had become officially intertwined with the House of Hapsburg) against her uncle/father-in-law, Maximilian III.
During her reign there was also the unification of all protestant churches in the British Isles under the entity of the crown, meaning that from that point forward the monarch is at the same time a member and not a member of all protestant denominations within his domains as their head (due to over a two centuries of developing differently, most protestant churches in Britain and Ireland considered the monarch as their head, so this was more of a formality and "making official what was already there")

His reign lasted a whooping 2 months and 12 days, as during his coronation over 40 barrels of gunpowder were exploded bellow the Abbey of Westminster as it was occurring by a group of conspirators (a colorful bunch of religious nonconformists (ergo, Catholics), revolutionaries (mostly nationalists due to the moves to centralize the government of the three kingdoms) and the odd disgruntled aristocrat), killing him, his wife, some of his children and a good chunk of the nobility (at least those of age) and political class in Britain

His main (and only) accomplishment as that he declared, in a short moment of lucidity, he should be called "Arthur the Second", as the semi-mythological King Arthur had been the first with that name to rule Britain

The last monarch of the independent kingdoms of England, Scotland and Ireland (although they remain a part of the monarch's full title) and the first monarch of the Empire of the Isles (called "British" as an exonym). She became ruler of the country after all those before her in the line of succession (her full brothers and her predecessor's children) died either in or due to the Bombing of the Abbey, and leaded the royalist forces during the Brief Civil War, having been beforehand a beloved princess (who after marrying for love remained in Britain) but not an important player in the government. A young but capable monarch who started ruling in a time of instability, her reign saw the restructure of the government under a new generation and the establishment of the empire, uniting the three kingdoms of the British Isles into a single state. Ruling during the trying times of the turn of the 18th to the 19th century, she also ruled during various wars in Europe and the Americas (including but not limited to the Imperial Civil War and the Mexican Revolution), and saw the expansion to the British Empire outside of North America and the odd territory in India and Africa
(Please think of this as a continuation of a line and not as me fooling around with the thread)
