Since you have mentioned Uniontown PA. The best place to start to find out about them is to go to the court house and ask for the naturalization records. Our ancestors were in a town not to far away and by getting the naturaization it will provide the names of the kids and the ship and when they arrived and the name of the town they came from. Our LUKACH changed their name to LUKAC/Lucasbut they are from Zubne, Zemplenski. I was able to locate some one 10 years ago to get the records from the church which provides their birth, baptism and parents names. In addition, the godparents names.
