Yes, in the index for Sv. Sid. there were SO many Liseks and Lisaceks. Same for Bylnice. But now that you have the link, you can simply go page by page looking for the right house number. (Did you click on the link and take a look?) Now that we have a date, and parents' names, some of us will probably help out by looking. Another thought: sometimes they got a year off when the document was issued for passport purposes. My grandfather's is that way, because he was the first birth of the year, and the priest simply wrote down the previous year. How often have we all done that writing checks in January of the new year? :) With your Joseph being in January, the actual year could be 1876. But it does sound like whoever gave you the data saw the actual records. You could see if they noted a book number and a page number.
BTW, Nr simply stands for Number, as in house number. These numbers are not sequential as in the US, but were possibly issued in the order the houses were built. The good news about Moravia is that most of the houses have two numbers on them, the historical one which would match these records, and the modern one.
