I think we may have some sort of family (Retzer) connection. I have in my files an Andreas Retzer, born abt. 1820 in Grafenried, Bohemia. This is very close to Eisendorf, and very close to Zelezna Ruda, (Eisenstine), Bohemia, now the CR. Andreas R. married twice,, first to ursula Baumel and then to Justina Baumler. Andreas and Ursula Retzer had three sons:
Johann * Abt. 1845 + April 20, 1878, Johanneshutte, Mrk Eisenstein Andreas * Abt. 1848, Eisenstein M: Theresia Wicki Heinrich * May 18, 1854, Grafenried + May 18, 1915, Ford City, PA.
I hope some of this information will be of some help. Danke, Thomas H. Semelbauer
