Hello!
I have a relative Anders Hernfrid Kjellgren who as far as I can see went back to the "old country" and picked himself a bride. They return in 1933, obviously after applying for citizenship beforehand, see ship record here:

The line under is Doris, his wife.
Now, is there a place I can find this passport application? As far as I can see, Ancestry records go no longer than 1925.
Best regards, Lars
