Yes, I do have Emma's passport. No reference to mother's maiden name there, but I believe it was Novak.
I found the arrival information this morning. Josef, Maria, Josef Jr. and Anna arrived under the name Wosinik. Birth dates were all correct, so I am sure this is them. They sailed from Hamburg on the Suevia.
The son, Josef was born in Pisik as per his obituary notice.
Every day I find some wonderful new piece to this puzzle. Thank you for your assisance.
