I tend to think that it did help grandduchessella, because it is known that queen Wilhelmina herself was certainly not fond of the Kaiser. She blamed him for not doing enough to prevent that terrible war and she had not a very high esteem of the Kaiser. She refused to meet him ever again even though he lived in her country. After WW ll queen Wilhelmina refused to speak ever a German word again for the rest of her live. I know that Juliana visited the Kaiser in Doorn and was a personal friend to grandduchess Kyra, wife of Louis Ferdinand. The kaiser was permitted to live first in castle Amerongen and later he bought castle Doorn. I am fortunate to live nearby so I have visited Doorn many times. It is wondefully decorated with furniture and other stuff of the German palaces of Wilhelm ll. It is a Dutch state museum since the end of WW ll. Crownprince Willie was in exile in the province of Zealand without permission to travel but I think that the crownprincess Cecilie, by that time, went her own way because I have never heard that she joined him in exile.
Prince Hendrik visited the Kaiser regularly while the latter was in exile.The visits started soon after the war,unofficially,and it was Hendrik who operated as a llaison,travelled to Berlin and saw to it the Kaiser's belongings came here by train.All 52 traincarriages full.Yes,Wilhelmina loathed the Kaiser,running off as he did was a shock to her,not worthy of a Monarch.
Wilhelmina didn't,officially,allow visits by members of her family untill 1927.The Crown Prince Wilhelm was,not in Zeeland,but in the top of the province Noord-Holland,in Wieringen(Wieringenmeer polderThijs
)a former island.He was confined there for quite a while,nothing at hand,except a few kids after he left.Crown Princess Cecilie never joined her husband there,occasional visits to her father-in-law,yes,nothing else.
