This site is sort of our name charts (it's "all" we've got ;-) ):
http://www.firstnamesgermany.com/
If you click on "hit lists for every year", for some reason the language will switch back to
German but you can search by year.
Edit: If you want to look at the statistics by decade, there is a column on the right side that reads "Jahrzehnte" (meaning "decades"). For example "1890er Jahre" in this case means the names most popular in the years 1890 to 1899.
Hope this helps.
