Anastasia Szulejko Poland/Russian >US/NJ/NY 1913

I am trying to locate any information about my grandmother Anastasia Szulejko (other spellings, Schulejko, Shulejko, Shuleiko, Shulaka, or anything similar). Anastasia immigrated to the US from Poland or Russia in 1913. She lived in Jersey City, NJ and married Nicholas Gladky in 1916. They had 3 children, William, Mary and Alexander Gladky. I have reached a brick wall with trying to find out anything more about the Gladky or Szulejko families. Any possible help would be greatly appreciated. Thanks
