Bearing on claims
Claim 7 (Uppsala doctorate): no Swedish press trace under either name. A newspaper silence is weak evidence for a student; the deciding records remain Uppsala University's matriculation and examination records and the Swedish church/police registration (husförhörslängder / mantalslängder) under the alias, 1910-1915.
