Hi, about your question about Westerburg: I didn't add the info you refer to, but User talk:Kelisi did, in his edit dated 6 June 2008. You can see that in the history of the article see here, accessible by the tab "history" above the article. You can ask Kelisi on his talk page where he got his info from, but I guess he translated it from German wikipedia. I saw on German wikipedia that the user who added the population data is de:Benutzer Diskussion:Asdrubal, maybe you can ask him. Markussep Talk 08:40, 18 March 2010 (UTC)
