I found a match who has Anna Ridder in their tree and since I have a 10th great grandfather also Ridder, whose father originated in Holland, I am fairly confident this must be same family since it's the closest in time shared familyname I could find in my match's tree and I don't have more recent ancestors from there. Older connections I did find but I suspect still that this is more plausible although I don't have other evidence for it than my dna-match's tree. And although my ancestor moved to Sweden at some point, they apparently kept contact with their original homeland. My ancestor was appointed as the governor of New Sweden in Delaware, USA. It would be pretty neat if the connection between their family in Holland and them could be made somehow. This is my Ridder ancestor:
Peter Hansson Hollender Ridder
