Tamshel, Tamsel

Does anyone know the meaning or translation of the word "Tamshell"? It might be a mispronounciation of Tamsel, but I'm not sure.

I found:
- "tamsel": arabic for "represent" (Google translator)
- "Schloss Tamsel": significant historical estate in the Brandenburg Neumark region (Wikipedia)
- "Timshel":  Hebrew word for ‘Thou mayest’ (http://www.wordnik.com/words/timshel)
