Hi, I stumbled on this page albeit by accident, looking for the obituary to my great-grandmother, Anna Horvat.
She came from Slovenia to the US, she had two older sisters who stayed there, and a brother Paul who she later discovered was living in Canada doing work for the railroad. She spent sometime in a boarding house in Philidelphia, PA. Later,she lived in Quakertown PA, and married Thomas Chobot.
I do not know when she arrived, nor if she had other siblings. Perhaps this Paul is the one you know?
