John Wrobel from Sanok Poland 1. Open

My grandfather – John Wrobel – was from Sanok Poland according to his immigration form. John Wrobel ( Americanized to Wrubel ) was born in 1880. John Wrobel’s mother was named Catherina Paczhowski ( spelling ? ).
My maternal grandmother – Mary Wanielista – was also from Sanok Poland. Mary Wanielista was born in 1893. Mary Wanielista’s father was named Michael Wanielista – her mother was named Katarzina Starymnski ( spelling ? ).
Both of there people died many years ago, and there are no living relatives that I know of that can give me any information.
Are there any records available of either of their relatives – parents – siblings – etc.?
