Annibach As I understand it regarding the cousins the Queen mother knew what had been done and condoned it, when it came to light years later the Queen distanced herself from the issue on the advice of her advisors and her mother. As the RF is wont to do - never complain, never explain. None of us have any idea why what happened happened and can only go on the information that we can read, which is also based on other people's opinions and insights. I am not blaming the Queen for what happened to them, but I am saying that they could have been treated differently when she did know of their existence ( I understand she thought they had died). It's a topic all on it's own really Annie. It doesn't make the Queen a bad person, but one who's had to temper herself against a lot of demands. This may, and I mean may have stifled her compassion in some ways.
In the case of Princess Alice - her own family treated her pretty shabbily and kept their distance. She spent many years living in poverty before ending up here under the care of the Queen. Her supposed mental illness was a source of embarrassment and though she was not treated badly as such, she was hardly embraced into the bosom of the family as the Queen's MIL. But again, I can only base my views on things that I've read. I wasn't there and can't judge, I can only have an opinion which is that the RF and the Queen don't have a public reputation as being the warmest, most inclusive family and therefore it is acceptable to discuss situations and people who may or may not have been adversely affected by that.
So maybe it's not a case of what the RF did to these people, but what they didn't do for them.
