Has that ever happened in history? Not just in Russia, anywhere. I've heard of other women bearing the heir for the king if the queen was unable, but never the other way around.
As was mentioned in the first post here, there are
rumors that Catherine the Great's son Paul was fathered not by her husband Peter but by her lover. In several years of marriage, they either had not concieved or had not even consummated the marriage, then suddenly she's pregnant. She did have several other children by her lovers over her reign, so the doubt is there. The Romanov dynasty may have ended back then!
The Queen Maud of Norway (Princess Maud of England) story was that a doctor allegedly claimed he impregnated her with his son's sperm in a turkey baster after she was unable to get pregnant by her husband. I have also heard that she and her husband didn't want to have sex, since they were very close first cousins and looked at each other as brother and sister, and they were only matched up for political purposes. Of course, all of these stories will go around, and we will never know the truth.
It would seem pointless to put the tsarina under the strain of producing a son, and if the son was not able to reproduce, just having someone else be the heir's father.
I agree! What's the point if the dynasty isn't really being carried on? I saw a letter to Dear Abby once where a lady had 3 girls and her husband was the last in his family and they needed a boy or the name would die out. She asked Abby if it was wrong of her to say she didn't want any more kids. Abby told her to adopt, but, uh, isn't that pointless for the reason? The child of a stranger would not be a carry on of the family line anyway so why bother? An illegitimate son of one of the daughters would do better than that!
