Otto II "the Red" Graf von Habsburg, Holy Roman Emperor

Otto II, Graf von Habsburg, Holy Roman Emperor

I'm curious about this one because he's supposedly a great grandfather, said to be the illegitimate son of George II King of England, according to one Wiki page I found that is not the one on his profile. While it does have a source that takes the reader to a site with a book ... not in English ... this is a hot mess to me. This must be a case of mistaken identity??

This is all the link you'll need to view Otto the Great and his family and their pages:
