There are no real names, there are only agreed names. I am "Vi" for my siblings and parents, "Vicente Aceituno Canal, son of Rufina and Andres" for the government, "Vicente Canal" for my work colleagues, "Chester" for my friends in the filmmaking clique. This is one of the failings of both Distributed Identity and Self Sovereign Identity, to try to be guardians of some "One Truth". There isn't any one truth, neither for names, nor addresses, with a few specific legal exceptions. There is only agreements valid for certain scopes.
