Every guess is as good as any other
Let’s just keep in mind that all immigrants had one objective
To get to the “Golden Medinah” “ Golden Country”
So, could be one person bought the tick. Could leave for whatever reason
Another one used it under the first person’s name
Or, simply, they thought to use Pauline name instead of an Yiddish/Jewish name
By the way, you mentioned Romania- what city?/ village?
The main thing is they arrived and made their new home USA.
All the best
STAY SAFE & HEALTHY
