I am also researching the Kollross family. From what I have been able to find, Barbara Kollross Kelnhofer's father (Karl), was a brother to my 4g grandmother (Eva).
The Czech Republic has some church records online. Those for Hammern, Bohemia (now Hamry) are at www.actapublica.eu
. You have to register to use the site, but it is free. Use the link below for helpful instructions as most of what you will see is in Czech or German.http://www.american.fm-search.org/index.php?option=com_conte...
Looking through the records is a tedious process. There is no index, so you basically will need to scroll through the records and look for familiar names. Most of the records I have looked at are in German. Some of the earlier records from the 1700s are in Latin, and I have found some later records in Czech. Other than the language, the handwriting itself can be difficult to decipher. If you are not familiar with German script, look for a site where you can learn about the lettering style.
When searching, you have to be sure to use the current Czech name of the town.
Here are the children of Karl Kollross and Anna Maria Oberhofer that I have found so far, and links to their births on the church records. (Again, you will need to register for the site to be able to see these.)

To continue to search other records in Hamry, from the main page click on the drop down arrow next to '...Brno' and select '....Plzni' and then click on 'abbilden". Then go down to 'signatur' and type 'Hamry' in the box and click on 'suchen'. This will bring up Hamry 01 through Hamry 16. They are not all labeled as to which records are in which location, so I will save you a little time and give them to you.
