OH! So they might be online at FamilySearch.org. Thank you very much. I personally have not needed to use either the Plzen archives or FamilySearch for my folks as they are all either in the Prague Archives or Brno Archives. Thank you so much.

Update: Aksamitnik's post stating that the records weren't online yet had not shown up at my end when I wrote this. Only Tonicek's. So this is amended to state that Isis00001 should watch for these records coming online, and hopefully she will find the records.
