Hello, I have in my fille next information:
Feil Anton (1860) and Feil Michael Ignatz (1854) both cabinet makers and sons of Feil Ignatz (1823) and Margaretha Gutterer (1828) emmigrated from Domazlice area to USA before 1880. Next siblings: Barbora (1856), Margaretha (1858), Frantiska (1865) and Karel (1867) perhaps stayed in Bohemia. Domazlice area is in southwest of Bohemia and lot of emmigrants from this area settled down in Wisconsin and Minnesota. Are they your ancestors???
All the best from Czech. Tony.
