I think I can help you. Your ancestors came from a town called "Münnichwies" - today Vricko in the slowakian republik - former Kingdom Austria-Hungary.
Me and a friend of me have written down the churchbooks from 1670 until 1946 here some informations:
Matthias Pischny (Pischny means "Stolzer" - german for a proud man) * 01.12.1863 + ? (USA I think) marriad with Rosalia born Kiepsel * 26.12.1847 + 18.11.1920 in Münnichwies.
They marriad at the 31.05.1886
Children: Matthias * 20.02.1887 + 03.05.1887, Josef * 20.02.1887 + 03.03.1887, Johann * 22.07.1888, Georg * 07.04.1882 and Anna * 10.11.1895 + 13.10.1897;
Grandparents: Johann Pischny alias Kuzmann * 22.10.1791 + 19.05.1880 Rosalia Pischny born Weiss (White) * 26.01.1819 + 04.09.1873 and Anton Kiepsel alias Weiss * around 1804 + 24.03.1876 and Maria Kiepsel born Schimko * around 1810 + 21.08.1873
hope to hear something from you soon: email@example.com
Would be great to get some old pictures from Matthias or Rosalia or even pictures from the family in Münnichwies - yours - Sebastian
