Looking for Relatives of Joseph L Pirog of Poland Russia

The closest we have come to researching our families roots or finding anyone/new information is my Great Grandfather Joseph L. Pirog and his parents; Leon Pirog and Julia Derbowicz. My great grandfather had four brother's that we are aware of at this point; Peter Pirog, John Pirog/Pirok, Walter Pirog, and Martin Pirog. On my great grandfather's WWI draft card it states that he is from Tomaszow, Lublin Poland Russia.

My family and I have a website for researchers, so please visit and register with us if you are also researching anyone with these surnames.
