Correcting an old mistake
For more than 20 years, I have carried the Motycin-Chicago Koutecky family’s father Vaclav Koutecky as the 1823 son of Martin Koutecky of Rousinov since this had been the believed situation by the family. My discovery of the 1880 census of Motycin proved that was not the correct Vaclav. The census is explicit that the Motycin Vaclav Koutecky was born 1840 at Modrejovice.

I had already found that 1840 Modrejovice Vaclav Koutecky’s birth and baptism record ( https://ebadatelna.soapraha.cz/d/11972/55 ) as I compiled my Modrejovice Families web page ( http://www.wwjohnston.net/famhist/modrejovice-all.htm ). He was the son of Vaclav Koutecky and Marie (non-marital daughter of Marie Wucer) and not of Martin Koutecky and Antonie Leitner at Rousinov.
