I been working on population of people in Denmark who used two surnames, example (Melchiorsdatter Stocklund) and I put both in 'birth name' spaced, assuming that I could find either one when searching on wikitree, but after adding a ton of sourced profiles I realized you have to put both of the surnames to find the profile.
And I cant find any way to search for either one, am thinking of just chaning them all to their uniqe surname, even if its not accurate so that people can find them easier.
