A Dutch bride! Based on her brother Huibert's profile that is linked in the link above, it is clear that he is much older (54 vs 32-33 for Sophie) - and assuming that
her brother Paul is the one working at PGGM, he is also quite a bit older: starting college (Amsterdam University of Applied Sciences) when his sister was only about 2 years old. They might very well have different mothers (in her case probably a Canadian mother? - her brother only identifies as 'Dutch' in the description on that website).
Her own LinkedIn-page provides an even more detailed overview of her study and work experiences (including working for the Office of the UN Secretary General) than could be highlighted in the Eurohistory article. It looks like both the future bride and groom are trying to make a difference in the lives of others that are less fortunate.
