If you'd like to find the German group, Black Bush, to see if there would be any conflict with your new band name, you might want to contact Mystic Seaport in Connecticut, where Black Bush performed at the 1999 Mystic Seaport sea music festival. Try them at:www.mysticseaport.org/communicate/tell.us.html
and put "Attn: Forebitter." (they are the singers who organize the fest)
