There is no archive in Komancza. You propably were in the civil registry offie. Archives and civil registry offices work according to different rules. You can not access the records in civil registry offices (you can get transcript of records of your direct anestors only) and you can access the records yourself in state archives. If I were you I would just go there again on your next visit and tell the clerk why you need these dates. I am think she/he would stretch the law a little. I would also contact the church in Komancza, maybe they would be able to help (they just may know the clerk, and I observed a few cases in which state officers were "more cooperative" if asked by the priest :).
As for the phone numbers, I do not know any online databases. I used to have a phonebook for year 2004 but I would have to look for it. I'll try to do it tomorrow and write you back.
