There is an artible in BB that describes how the Danish Queen Ingrid took Silvia under her wings before she married Carl Gustav:

Few know that Silvia Sommerlath Ingrid was under the protective wings at Fredensborg before his wedding to Carl Gustaf. When the Swedish queen tries to advise the Crown Princess Victoria's future husband Daniel Westling in the difficult art to enter the royal scene as non-permissible, so will many of the advise will come directly from Queen Ingrid.
Silvia in his time came to Scandinavia in order to be married to Swedish Carl Gustaf, and it was Queen Ingrid, who took her in and showed her tenderness and care:
- I was engaged and the King and Queen Ingrid invited me to stay with her for three days. Considerate as she was, she had also invited Princess Margaret, King's sister. I saw immediately an unprecedented warmth of Queen Ingrid. I had expected that the Queen would send a chauffeur to pick me in Copenhagen. Instead, she personally also, and kept her car in the square beside the aircraft.
When we were driving away, she saw that I sat where I was in the car. She taught me the royal protocols and rules for - without words - to show how it should be.
She showed me great affection, and that she cared about me. Queen Ingrid was always there, and it meant a lot to me, says Silvia to the Swedish magazine. -
It is strange to see it in Queen Ingrid - well, for me. The queen looks stern and no-joke. Nice to know that she was kind enough to help a "newbe" (Silvia) in the time of stress and uncertainty
