Orphaned?

I have yet been able to get past my great-grandparents. I am beginning to wonder if maybe they were orphans when they left Austria and Poland. I really hope that is not the case with my ancestors because then I will probably find nothing more than what I have found. It does sound kind of romantic that to orphans found each other and married. They most likely did not marry for love, but you never know stranger things have happened to my family.
