What if Empress Matilda has a children with Henry V of the Holy Roman Empire, would she try to marry one of her children with that of Stephen of Blois?
It's a solution, especially if she had a single daughter. That said, they'd probably be more focused on the HRE and the threat of absorbing England into the HRE might actually strengthen Stephen's cause (unless Henry V was still alive at Henry II's death, thus inheriting the throne jure uxoris).
Depends, would the Church of the time be willing to countenance the marriage of first cousins? As Velasco says if she had a single daughter and could arrange it that would neatly solve the problem - she would be ineligible to inherit any territories in the Empire thanks to Salic law or be elected to the Imperial crown and so would have only a, potentially tenuous, claim on England. The question would then become what effects does the Anarchy not occurring have on England?What if Empress Matilda has a children with Henry V of the Holy Roman Empire, would she try to marry one of her children with that of Stephen of Blois?
