Here's something I've been working on with @The_Most_Happy recently - a Royal family in a world where Victoria becomes Queen in 1820 and is raised by the Cambridges.
Still a work in progress, but I may build a shorter TL around it someday...

Other Notes: I never understood why Victoria didn't use her father's title for any of her sons OTL, so here it is being used for her second son, Arthur, though I have given both the younger boys Scottish Dukedoms as well, echoing what Victoria did with her younger sons OTL.
George of Cambridge never marries Sarah Fairbrother, leaving him free of scandal and able to wed his widowed cousin in 1851 - a different marriage doesn't improve Alexander's health any! Victoria is rather more level-headed TTL, but she still enshrines it in law that all children born into the male lines of the Royal Family must contain variations of Victor/Victoria or Alexander/Alexandra/Alexandrina in their names after Alexander's death - hence the plethora of similar middle names for all children born post 1848.
And I will work out the daughters' children when I need to! Though I suspect, being out of the country, they might escape the plethora of Victors/Victorias/Alexanders/Alexandra/Alexandrinas...
