While I thoroughly enjoy the series, did anyone else find the story line of Marigold completely unbelievable? Even though Lord & Lady Grantham were more liberal minded that other aristocrats of the day, there is absolutely no way they would have allowed Edith to keep an illegitimate baby, no matter how much they might love her.
Especially as the whole point of the aristocracy was blood lines, inheritance and legitimacy. For an Earl's daughter to give birth out of wedlock would have meant she would have been forced to give the child up for adoption end of story. To not do so would have caused such a scandal, the entire family would have been outcasts.
