Thanks -- I wondered about that as I was typing my response.
On to a different spelling matter, however, it is Battenberg, not
Battenburg. This refers to your recent history lesson
regarding Winsor/Windsor (see http://en.wikipedia.org/wiki/Mountbatten).
In German, Berg refers to mountain &
Burg to castle.
Best wishes,
Eric
