User blog:Imperium Guy/British-German Union

I would just like to say this blog has been inspired by Bob, although the idea has been in my head for a long time. So here it is:

Is it possible that Germany and Britain could have been united at a time in history which would continue on to present day? There are times when this could be a good option:

I would also ask if anyone has another idea if this could work and for your two pence!
 * 1) Mid-1st Millennial: With the leaving of the Romans, Anglo-Saxons came in. Was there a possiblity that this could have lead somehow into a British-German Union? This would be when there would be a monarch of England who might invade Saxon lands or maybe they might unite with England maybe?
 * 2) Henry VIII: Before Henry married Arthur's (his brother) widow, he had the offer of marrying Eleanor of Austria (daughter of the current Holy Roman Emperor). If he had married Eleanor, what would the fate of Germany have been? I would like to think he would still break away from the Chatolic Church some how (I do have an idea).
 * 3) Treaty turned Union: Britain and Prussia traditionally had good relations uptil the First World War, what if in the Nepoleanic era, or soon afterward, both countries entered a personal union? This would mean Prussia would have eventually had British backing in its wars and would have managed to unite northern Germany quicker and Prussia would have been a kingdom in the UK.
 * 4) Victoria II: The idea being explored in the TL The Anglo-German Union, I would like to ask if this idea could work out. It stands a good chance, I would say.
