Teresov family

Previously I thought my Grandfather and his brother came from Podmokly & Hut due to info I got from their ship manifest. This information was incorrect, they both were born in Teresov- Austria Hungray in the late 18 hundreds. This information I found in their Naturalization records and Marriage license. My question is this, what parish do I search in to find relatives and family history. ( Drhaonuv Ujezd or Mlecie parish). I’m not even sure if these are the local parishes or if the spelling is correct. Any one whom can guide me in the wright direction would be greatly appreciated. I been doing this for many years looking in the incorrect town, now I know why I couldn’t find my family. Thank you, Kathryn
