The website given by jen is for Radčice u Železného Brodu, not the Radčice Robert is looking for (I only know this through PMs, by the way). You want the Radčice in Plzeň. I found a website for the archives in Plzeň, but only in Czech: http://info.plzen-city.cz/article.asp?itm=190
Thanks for the assist, and yes, it's always good to have as much info as possible about a town's location, as there are often multiple towns with the same name
