6. Frederick II and Maria Theresa How is this easy? I seriously looked for like at least an hour for a connection but all the names are the same but none of the people are and all the family trees I found didn’t have Prussia’s family tree so I couldn’t even like anyone from there to Austria's. I can link Maria Theresa to about everyone else except Frederick II. Not even joking I think the only connection they have is in wikipedia it said he proposed to Maria Theresa of Austria in return for renouncing the succession but in another source I found it said Frederick II married Elizabeth Christine. In my Louis XIV and Charles I chart I have an Elizabeth and Christine but no Elizabeth Christine and since they didn’t have any children I can’t go that way and I tried to work my way up from Frederick about a million times and ways and nothing worked and I worked up and down for Maria Theresa and I just don’t think it’s humanly possible, I think they may be the only two members of the royal world or whatever who aren’t related.
