MARY OF DENMARK
Prince Henrik of Denmark, son of Prince Joachim and Princess Marie of Denmark
Josephine Flemming, daughter of Caroline and Rory Fleming
Holger Redtz-Thott, son of Helle and Otto Redtz-Thott
Isn't it likely that she is godmother of one of her sisters children as well?
Did her sisters' children get christened? In fact, was Mary christened as a baby? For some reason I seem to think she wasn't, but actually I have no idea.
I don't know about her nieces and nephews, but Mary's family is Presbyterian. She converted on marriage.
