Kloos- Austria Hungary

I'm presently researching a Margaret Kloos, born in 1890 Austria Hungary. She was the daughter of Matthias Kloos and Catherine Henning, also of Austria Hungary. She eventually married Martin Paul and settled in Ellwood City, Lawrence County, PA. I don't lnow when she came to America. She had a brother, Matt Kloos, who also lived in Ellwood City. According to the 1920 census he came to America in 1910. Does anyone know of this family?
